San Francisco International Airport is having one of its worst days of 2026. The departure boards are red and yellow from one end to the other. United Airlines has delayed 25% of its entire SFO schedule. British Airways and Emirates are recording 100% delay rates on every flight they operate today. And the damage reaches ten countries across four continents.
San Francisco International Airport descended into operational chaos on June 5, 2026, as 337 flight delays and 5 cancellations cascaded through terminals packed with thousands of stranded passengers. The disruptions rippled across domestic and international networks, touching 10 countries and devastating travel plans for everyone from weekend leisure travelers to business executives racing to board long-haul flights.
Among airlines operating at SFO, United Airlines is the most impacted, with 126 delays and 5 cancellations, representing 25% of flights delayed. Regional carrier SkyWest also faces substantial disruptions, with 57 flights delayed (31%), while Southwest Airlines has 45 delays affecting 62% of its flights. Other carriers with high delay rates include American Airlines (25 delays, 30%), Delta Air Lines (17 delays, 20%), and Breeze Airways (6 delays, 85%), highlighting operational challenges across both major and regional carriers.
This is Day 66 of the US aviation crisis — and today’s SFO numbers are the worst at any single US airport this week, surpassing yesterday’s Denver (164 total) and Philadelphia (88 total) by a significant margin. If you are flying to, from, or connecting through San Francisco today, this guide tells you everything you need to know, carrier by carrier, route by route, and right by right.

To understand why today’s SFO disruption is exceptional rather than routine, the numbers need to be placed in their operating context.
The disruption struck at a time when San Francisco International Airport is ramping up for peak summer travel, magnifying the impact on passengers and airline schedules. The pileup of delays also coincided with elevated winds over the Bay Area and ongoing air traffic management initiatives that can reduce airport capacity at busy hubs. When that happens during peak travel periods, airlines have limited room to absorb additional strain, and even relatively modest interruptions can cascade across routes and time zones.
SFO handles approximately 55 million passengers per year and operates as United Airlines’ primary West Coast hub. On any given day, United operates the majority of SFO’s gate positions and the majority of its international departures. When United runs in distress at SFO — as it is today, with 25% of all United flights delayed — the cascading effect reaches every domestic US market United serves from San Francisco and every international long-haul route in United’s SFO transpacific and transatlantic schedules.
The 337 total delays today compares to:
Today’s SFO figure is therefore roughly 5–7 times the airport’s normal operational disruption level — an extraordinary spike that reflects the combination of weather, capacity, and structural summer peak load operating simultaneously.
United Airlines is SFO’s largest carrier by far — operating the majority of the airport’s domestic and international gate positions and running the preponderance of transpacific services from the Bay Area. Today’s 126 delays and 5 cancellations represent a 25% disruption rate across United’s full SFO schedule.
United Airlines, SFO’s largest tenant by flight count and passenger volume, was especially exposed to the June 5 disruption. Any delay on this leg can compromise onward connections to destinations such as Singapore, Manila, Cebu and other cities in the Philippines, as well as major business centers in Europe and the Gulf states.
United’s SFO international services affected today:
United operates the following long-haul routes from SFO that are affected by today’s disruption:
| Route | Service | Impact |
|---|---|---|
| SFO → Tokyo Narita (NRT) | Daily | Delayed |
| SFO → Tokyo Haneda (HND) | Daily | Delayed |
| SFO → Osaka Kansai (KIX) | Japan | Delayed — Kansai confirmed 100% delay |
| SFO → Singapore (SIN) | Daily | Delayed — Singapore affected |
| SFO → Manila (MNL) | Philippines | Delayed — Philippines affected |
| SFO → Shanghai Pudong (PVG) | China | Delayed — China in affected countries list |
| SFO → Frankfurt (FRA) | Germany | Delayed — Germany in affected countries list |
| SFO → London Heathrow (LHR) | UK | Delayed — UK in affected countries list |
In addition, passengers connecting through the US, Singapore, Philippines, UAE, Ireland, Denmark, United Kingdom, Japan, Germany and China are facing knock-on delays, impacting both short-haul and long-haul travel.
United’s 5 SFO cancellations today: All five cancellations are attributed to United Airlines — meaning United is the only carrier recording outright cancellations at SFO today. These cancellations displace the highest number of passengers per disruption event, given United’s large-gauge aircraft on transpacific and transatlantic services.
Reddit reaction: Reddit user posted in r/travel: “Just got the cancellation email. SFO is a nightmare right now. United is offering rebooking but everything is full.”
United passengers action:
Regional carrier SkyWest faces substantial disruptions, with 57 flights delayed (31%) of operations.
SkyWest is today’s second-most disrupted carrier at SFO by volume, and its 31% delay rate reveals a systemic problem rather than isolated incidents. SkyWest operates regional feeder services at SFO under three different brand identities — United Express, Delta Connection, and Alaska Airlines — meaning its disruptions today appear under the banners of three separate major carriers on passenger booking confirmations.
The practical consequence: passengers who believe they are flying United, Delta, or Alaska this afternoon from SFO on a short-haul regional connection may actually be on a SkyWest-operated aircraft experiencing a 31% disruption rate. If your booking confirmation shows a CRJ-200, CRJ-700, CRJ-900, or E175 aircraft and your flight number begins with a regional range code, you are likely on a SkyWest operation.
If your SkyWest flight is delayed or cancelled at SFO: Contact the marketing carrier (United, Delta, or Alaska — whichever name is on your ticket) for rebooking. The marketing carrier bears full customer service and rebooking responsibility for SkyWest-operated code-share flights, even though the aircraft and crew are SkyWest’s.
DOT rights for SkyWest-operated delays: The same DOT rights apply regardless of whether SkyWest or the marketing carrier actually operates your flight. If the cause is controllable, you are entitled to meals (3+ hour delays), hotel (overnight delays), and full cash refunds (cancellations).
Southwest Airlines has 45 delays affecting 62% of its flights.
Southwest’s 62% delay rate at SFO today is the second-highest percentage disruption figure among all carriers at the airport — only Breeze Airways (85%) is higher. In practical terms, Southwest’s 62% figure means that almost two in three Southwest flights operating at SFO today are running behind schedule.
This is particularly notable context given Southwest’s permanent exit from Chicago O’Hare yesterday (June 4). While Southwest no longer operates from O’Hare, its West Coast operations remain fully active — and SFO is an important Southwest West Coast node, connecting California with Southwest’s core domestic network.
Southwest’s SFO routes most affected today: San Diego, Las Vegas, Phoenix, Denver, Los Angeles, and Portland domestic connections — all key leisure corridors from the Bay Area in peak summer.
Southwest passengers: southwest.com → Manage Reservations → Change Flight. Southwest’s no-change-fee policy means all rebooking is penalty-free regardless of cause. No same-day standby fee applies.
American Airlines records 25 delays representing 30% of its SFO schedule today.
American Airlines operates a secondary presence at SFO compared to its primary West Coast base at Los Angeles International. Nevertheless, a 30% delay rate means almost one in three American flights at SFO today is disrupted — a significant operational failure for what should be a straightforward operation at a hub where American is not the dominant carrier.
American’s SFO delays today particularly affect connecting passengers using SFO as a West Coast entry point for onward American domestic connections to its Phoenix (PHX) and Dallas–Fort Worth (DFW) hubs, and passengers on American’s SFO–London Heathrow service operated in conjunction with British Airways via the Atlantic joint venture.
American passengers: aa.com → My Trips → Change Trip. For delays of 3+ hours caused by controllable American operations, meal vouchers are available at the American service counter in SFO’s Terminal 2.
British Airways has reported 100% delays on the flights operating from or to SFO, showing that overseas routes are particularly affected today.
British Airways operates SFO–London Heathrow as its primary California service — one of the most commercially important transatlantic routes from the West Coast. A 100% delay rate means every single British Airways flight operating at SFO today is running late. This is the maximum possible disruption level for a carrier’s operations at an airport.
The BA SFO disruption has a direct and immediate impact on UK-bound passengers from the Bay Area and on passengers connecting beyond London Heathrow to UK domestic destinations, European connections, and onward long-haul services. San Francisco is home to a significant British professional community — technology sector workers, financial services professionals, and academic staff — and BA’s SFO–LHR service is their primary route home.
UK261 compensation for British Airways passengers:
British Airways is a UK-registered carrier. UK261 applies to all BA flights departing from any airport worldwide — including SFO. For delays of 3+ hours at London Heathrow caused by controllable British Airways operational decisions, every affected passenger is entitled to:
| Route distance | Delay threshold | UK261 compensation |
|---|---|---|
| SFO → London Heathrow | Over 3,500km | £520 per passenger |
Today’s BA SFO disruption, if caused by controllable factors rather than extraordinary circumstances (weather, ATC), qualifies for full UK261 compensation. Bay Area winds and air traffic management restrictions at SFO are generally classified as meteorological/ATC factors — meaning BA may argue extraordinary circumstances. However, if the specific delay affecting your flight is operationally driven (crew unavailability, aircraft maintenance, scheduling failure), the £520 right is fully applicable.

Emirates has reported 100% delays on the flights operating from or to SFO, showing that overseas routes are particularly affected today.
Emirates operates SFO–Dubai International as one of its premium North American gateways. A 100% delay rate at SFO means Emirates’ entire SFO operation is disrupted today — affecting passengers travelling between the Bay Area and Dubai, and critically, the large volume of connecting passengers using Emirates’ Dubai hub to reach destinations across the Middle East, South Asia, Africa, and Australia.
Emirates’ SFO–Dubai service is not just a point-to-point route. It serves as the backbone connection for:
Any delay to the SFO–DXB leg today cascades into missed connections at Dubai International for all of these downstream markets.
Publicly available schedules show Emirates and other Gulf and European carriers adjusting departure and arrival estimates to reflect the evolving situation at SFO. For all of these airlines, San Francisco remains a strategic entry and exit point for high-yield corporate travelers and long-haul leisure demand.

Important for Australia-connecting passengers: If you are connecting SFO–DXB–Australia on an Emirates–Qantas codeshare, today’s SFO delay directly affects your Dubai connection timing. Emirates duty of care at Dubai includes hotel accommodation and meals for overnight delays — contact Emirates at Dubai Airport arrivals if your connection is missed.
Delta Air Lines has 17 delays representing 20% of its SFO schedule.
Delta’s SFO disruptions today primarily affect its domestic California network and connections through its Salt Lake City (SLC) and Seattle (SEA) hubs. Delta began its new LAX–Hong Kong service yesterday (June 6 launch — one day from now) and is managing a heavy operational push to ensure that aircraft and crew are positioned for that historic first departure, adding operational complexity to its West Coast schedule.
Delta passengers: delta.com → My Trips → Change or Cancel.
Air Canada Rouge has reported 100% delays on the flights operating from or to SFO.
Air Canada Rouge operates leisure-configured services on the SFO–Toronto Pearson (YYZ) and SFO–Vancouver (YVR) routes. A 100% delay rate today means every Air Canada Rouge flight at SFO is disrupted — affecting Canadian passengers returning home from California and US passengers connecting to Canadian destinations.
APPR rights for Air Canada Rouge passengers: Canadian APPR (Air Passenger Protection Regulations) apply to all Air Canada and Air Canada Rouge flights. For delays of 3–6 hours caused by controllable factors: CAD $400 compensation. For delays of 6–9 hours: CAD $700. For delays of 9+ hours: CAD $1,000.

Breeze Airways records 6 delays representing an 85% disruption rate, highlighting operational challenges across both major and regional carriers.
Breeze Airways is a Utah-based ultra-low-cost carrier that operates a limited SFO schedule. An 85% delay rate today is the highest percentage figure of any carrier at SFO — meaning virtually every Breeze flight is running late. While Breeze’s total volume is lower than United’s, its percentage impact on passengers is the most severe of any carrier in the airport today.
Breeze passengers are particularly vulnerable because the airline operates with limited spare capacity and recovery options compared to majors like United or Delta — when Breeze runs late, it stays late, and the recovery curve is slow.

| United Kingdom | SFO → London Heathrow | British Airways | 100% delay rate |
| UAE | SFO → Dubai International | Emirates | 100% delay rate |
| Ireland | SFO connections via Dublin | Via United / Aer Lingus | Cascading from Dublin chaos today |
| Denmark | SFO → Copenhagen | Via SAS / United connections | Copenhagen route disrupted |
| Japan | SFO → Tokyo Narita / Haneda / Osaka Kansai | United · ANA | Kansai confirmed 100% delay |
| Singapore | SFO → Singapore Changi | United | Service disrupted |
| Philippines | SFO → Manila | United | Service disrupted |
| Germany | SFO → Frankfurt | United / Lufthansa | Route affected |
| China | SFO → Shanghai / Beijing | United / Air China | China in confirmed affected list |
| Canada | SFO → Toronto / Vancouver | Air Canada Rouge | 100% delay rate |
Note for UK, Irish & Danish passengers at SFO: Today’s European disruption is compounding today’s Bay Area chaos. Dublin Airport is simultaneously experiencing 207 delays and 4 cancellations on June 5, and Brussels Airport recorded 170 delays yesterday. UK passengers connecting SFO–LHR–onward European destinations face a double-disruption risk today — at both ends of their journey.
The pileup of delays also coincided with elevated winds over the Bay Area and ongoing air traffic management initiatives that can reduce airport capacity at busy hubs.
San Francisco Bay Area’s geography makes SFO uniquely vulnerable to wind-related capacity reductions. The airport’s runways are oriented to take advantage of prevailing westerly winds — but when winds shift direction or increase beyond standard parameters, runway configurations must change. A configuration change at SFO typically reduces the airport’s arrival rate from approximately 60 aircraft per hour to 30–35 — cutting capacity in half during the period of wind disruption.
On a day when SFO is operating at peak summer demand with maximum scheduled arrivals and departures, a configuration change that halves arrival capacity creates an immediate queue of inbound aircraft holding over the Bay. Every aircraft that holds burns fuel and accumulates delay time. When it finally lands, it arrives late, its turnaround is compressed, and its outbound departure is delayed. Within 2–3 hours, a wind event that lasted 90 minutes has created delays across the entire afternoon schedule.
In addition to wind-driven capacity reductions, today’s SFO disruptions are being amplified by FAA Air Traffic Management Initiatives — formal traffic management programmes that control the rate of arrivals into congested airports.
The FAA’s Ground Delay Programme (GDP) at SFO today means aircraft scheduled to depart for San Francisco from other US cities are being held at their origin airports before departure, adding scheduled delay time before passengers even reach the gate. For a passenger flying Dallas to San Francisco this afternoon, the delay may begin at Dallas Fort Worth — not at SFO.

The sheer scale of the disruption marks one of SFO’s worst days in recent memory. Unlike isolated weather events that typically resolve within hours, today’s chaos appeared systemic — affecting carriers, destinations, and airport operations in ways that suggest deeper operational challenges.
June 5 is Day 12 of peak summer travel at SFO. Every airline has filed its maximum permitted schedule — meaning there is virtually no spare aircraft or crew capacity to absorb disruptions. On a normal spring or autumn day, a 90-minute wind event at SFO produces a 90-minute recovery. On a peak summer Friday, the same event produces a 4–5 hour tail, because there are no spare aircraft to replace delayed aircraft and no gaps in the schedule where the system can catch up.
San Francisco International Airport operates four terminals: Terminal 1 (Board A, B, C, D), Terminal 2, Terminal 3, and the International Terminal (Boarding Areas A, G). Airlines are spread across terminals as follows:
| Terminal | Key airlines | Gate areas |
|---|---|---|
| International Terminal | United international · British Airways · Emirates · Lufthansa · Air Canada · Singapore Airlines · ANA | Boarding Area A (domestic connection) · Boarding Area G (international) |
| Terminal 3 | United domestic · United Express (SkyWest) | Boarding Areas E, F |
| Terminal 1 | Southwest · Alaska Airlines · Delta Air Lines | Boarding Areas B, C, D |
| Terminal 2 | American Airlines · Virgin America legacy gates | Boarding Areas D, E |
Key services during disruption:
United Club (T3, Level 3): Open to United Club members, United Business class passengers, and Star Alliance Gold members. Offers rebooking assistance, phone charging, food and beverages. On a day like today, expect capacity pressure in the lounge — arrive early if you have access.
United service desk (T3, Level 2): For in-person rebooking. Expect queues of 45–90 minutes today. Use united.com or the United app instead for faster resolution.
International Terminal rebooking desks: British Airways, Emirates, and Air Canada Rouge check-in counters are located in the International Terminal check-in hall. On a day with 100% delay rates on these carriers, counter staff will be overwhelmed — use airline apps first.

Cancelled flights (United’s 5 cancellations today):
Every passenger on a United-cancelled flight today at SFO has three immediate rights under the DOT’s 2024 final rule:
Right 1 — Full cash refund: United must return your full fare to your original payment method within 7 business days. This right applies even on non-refundable tickets, even if United offers you a travel credit as the “first option.” Say: “I am requesting a full cash refund under DOT regulations.”
Right 2 — Penalty-free rebooking: United must rebook you on the next available United service. You do not pay a fare difference. If the next available United service is unacceptably late, request rebooking on a competing carrier — United has been increasingly accommodating this request under DOT monitoring.
Right 3 — Controllable delay amenities: If United’s cancellation or delay is caused by factors within its control (operations, crew, maintenance) rather than extraordinary circumstances (wind, ATC), United must provide:
For significant delays (not cancellations): The DOT’s 2024 rule creates refund rights for delays of 3+ hours domestic / 6+ hours international caused by controllable factors. If United delays your SFO flight by 6+ hours on a transpacific route due to a controllable operational factor, you are entitled to a full refund even without a cancellation.
British Airways is a UK carrier. UK261 applies to all BA flights departing from SFO — a non-UK airport — operated by a UK carrier.
For BA SFO delays of 3+ hours at London Heathrow caused by controllable factors: £520 per passenger (SFO–LHR exceeds 3,500km).
Duty of care at SFO (regardless of cause): BA must provide meals and refreshments at the airport for delays of 2+ hours, two free telephone calls or emails, and hotel accommodation if an overnight stay is required. These rights apply even if BA classifies the delay as an extraordinary circumstance.
File UK261 claim: ba.com → Customer Support → Claim Compensation. Or via Bottonline: bottonline.co.uk. Or AirHelp: airhelp.com.
For EU-registered carriers operating from SFO (Lufthansa, Air France, KLM, Swiss, Austrian, etc.), EU261 applies on all departures from SFO as the departure is from a non-EU airport on an EU carrier.
For delays of 3+ hours at the final EU destination caused by controllable factors: up to €600 per passenger (SFO to any European hub exceeds 3,500km).
File EU261 claim: Directly with the airline’s customer relations portal, or via AirHelp (airhelp.com) on a no-win, no-fee basis.
Canadian APPR applies to Air Canada Rouge’s SFO services. For controllable delays:
File APPR claim: aircanada.com → Contact Us → Delay/Cancellation Claim.
Step 1 — Check your flight status immediately at your airline’s official app — not third-party aggregators. Status on airline apps updates in real time. On a day with 337 delays at SFO, status changes frequently and early notification is the difference between catching a rebooking option and missing it.
Step 2 — Rebook online before going to the airport. Every airline service desk at SFO is experiencing significant queue times today. United’s app, Southwest’s app, BA’s app, and Emirates’ portal all have the same rebooking inventory as counter staff — and zero queue time. Complete your rebooking from home or your hotel.
Step 3 — Know your delay cause before you claim. Wind and ATC are generally classified as extraordinary circumstances — limiting your compensation rights. Operational and crew issues are controllable — activating full DOT/UK261/EU261 rights. Ask airline staff for the official delay reason in writing when you check in or board.
Step 4 — Keep every receipt. Food, drinks, phone calls, transport, hotel — anything you pay out of pocket because of today’s SFO disruption is potentially reimbursable. Under duty of care provisions (UK261, EU261) airlines must reimburse reasonable expenses caused by significant delays regardless of compensation eligibility.
Step 5 — File your claim promptly. DOT claims: airconsumer.dot.gov. UK261: ba.com → Customer Support. EU261: airline portal or AirHelp. APPR: aircanada.com. Claims filed within 30 days of the disruption are processed faster.
