Your flight to Denver was cancelled. Denver is 45 minutes away by car. And even if you somehow got there — the O’Hare connection you were flying to has 207 cancellations waiting for you.
That is the situation at Colorado Springs Municipal Airport (COS) today, June 18, 2026 — Day 79 of the US aviation crisis. Southwest Airlines and SkyWest Airlines have cancelled 4 flights and triggered multiple severe delays at COS, severing the airport’s connections to Denver, Dallas, Chicago, and Phoenix simultaneously. The airport’s entire viable network — all 17 nonstop destinations, 40 daily departures, served by just five airlines — is under stress from a cascade that did not originate here. It originated at Chicago O’Hare, 1,000 miles east, where 207 cancellations and 1,218 delays have collapsed the hub that COS depends on for its own onward connections.
Colorado Springs does not normally make aviation news. It is the second-largest airport in Colorado, a military city airport that serves Fort Carson, Peterson Space Force Base, the Air Force Academy, and the civilian population of El Paso County. Its terminal has one concourse in active commercial use. It handles roughly 40 departures a day. On a normal day it does not appear on any disruption tracker. On June 18, 2026, it is appearing on FlightAware — and what it illustrates is not really about Colorado Springs at all. It is about what happens at the very end of the aviation network when the nodes at the centre collapse.
Colorado Springs is the canary. O’Hare is the coal mine.

To understand what is happening at COS today, you need to understand how aircraft get to Colorado Springs in the first place.
Colorado Springs does not have a maintenance base for Southwest Airlines or SkyWest. It does not have significant aircraft overnight positioning. Every aircraft that arrives at COS today flew in from somewhere else — from Dallas, from Denver, from Chicago, from Phoenix — as part of a rotation that started hundreds of miles away. If that aircraft does not arrive at COS, there is no flight out of COS. There is no spare aircraft on the ground. There is no backup. The flight is cancelled.
That is what happened today.
Southwest Airlines is operating its largest Colorado operation out of Denver — its mountain west hub following its exit from O’Hare on June 4, 2026. Southwest’s Denver operation today is absorbing the same FAA Ground Delay Program cascade that is hitting O’Hare. Southwest cancelled 4 aircraft at Denver and is generating 200+ national delays. The Southwest aircraft that was supposed to fly from Denver or Dallas to Colorado Springs this morning — completing its rotation before the return leg — never arrived. COS gets the cancellation.
SkyWest operates as United Express on the Colorado Springs routes. SkyWest’s June 18 national performance is the worst of any carrier at O’Hare today: 56 cancellations nationally and 116 delays. SkyWest’s thin-frequency operation at COS — typically 1–2 daily services per route — means a single cancelled inbound aircraft produces a 100% cancellation rate on that service for the day. The crew that was supposed to operate the outbound COS departure was on the inbound aircraft that never arrived.
The result: a small airport in Colorado that did nothing wrong, whose ground staff reported for work, whose terminal is fully operational, and whose passengers arrived on time — is cancelling flights because a thunderstorm hit Chicago.
Colorado Springs Municipal Airport serves a city of approximately 480,000 people at 6,187 feet elevation — the second-highest major commercial airport in the continental United States after Denver itself. It sits 7 miles east of downtown Colorado Springs, accessed via Powers Boulevard and Highway 24.
The airport has one terminal with one commercially active concourse, Gates 1–12. There is a second concourse (Gates 14–18) that exists but is not in commercial passenger use — do not be confused if you see it on a map. All commercial flights depart and arrive through the single active concourse.
The airport’s commercial significance: COS is not a hub. It is a spoke airport — a city that generates and receives passengers but does not connect passengers through it. Every COS passenger is either originating their journey here or ending it here. Nobody connects through Colorado Springs. This structural reality means that when flights cancel at COS, there are no connecting passengers to rebook onto the same airline’s next through-service. Everyone in the terminal today is going somewhere specific — Denver, Dallas, Chicago, Phoenix — and their only option on that route has just been cancelled.
COS’s relationship with Denver: The two airports are 45 miles apart on I-25. Denver International Airport (DEN) is one of COS’s most popular destinations, with United operating the COS–DEN shuttle — a 52-minute flight that serves passengers who need to connect at DEN for onward domestic and international travel. The geographic proximity creates a painful irony on disruption days: the flight to Denver is cancelled, but Denver itself is reachable by road in under an hour. The airport — an institution designed to save people the drive — has today made the drive the better option.
Southwest is the largest carrier at Colorado Springs by route count, operating 8 nonstop destinations from COS: Dallas Love Field (DAL), Houston Hobby (HOU), Las Vegas (LAS), Phoenix Sky Harbor (PHX), Denver (DEN), San Antonio (SAT), San Diego (SAN), and St. Petersburg/Tampa (PIE).
Today’s Southwest cancellations at COS are directly tied to Southwest’s national June 18 positioning crisis. Southwest exited O’Hare on June 4, 2026, concentrating its Chicago-area operation entirely at Midway. But Southwest’s Denver hub — its largest Rocky Mountain base — is absorbing today’s FAA GDP cascade. Southwest Airlines grounded 4 aircraft at Denver today, with the ripple effect spreading over 200 delays from Denver to every major airport in North America.
The Southwest routes most disrupted at COS today:
COS → Dallas Love Field (DAL): Southwest’s flagship COS leisure route, connecting Colorado Springs to its Texas network. A cancelled COS–DAL service today cannot be recovered until tomorrow’s rotation — there is no Southwest spare aircraft at COS to substitute.
COS → Denver (DEN): The shortest and most frequently used Southwest route from COS. A flight that takes 52 minutes and serves passengers who need DEN connections for onward travel. With Southwest’s own Denver operation disrupted today, the COS–DEN service offers a cancelled departure into a disrupted arrival airport — a double failure.
COS → Las Vegas (LAS) and Phoenix (PHX): Southwest’s leisure desert routes from COS. Cancelled today as Southwest’s western rotation aircraft failed to position into COS on schedule.
Southwest passenger action: Southwest has no desk presence at COS outside of flight operations. Rebook at southwest.com or call 1-800-435-9792. Southwest’s rebooking policy for weather-adjacent cancellations typically offers free same-day or next-day rebooking to the same destination, or a full refund. Given today’s scale of Southwest disruption nationally, next-day availability on COS routes may be limited — book immediately.
SkyWest operates the Colorado Springs routes under the United Airlines flight code — meaning passengers booked on United who are flying COS–DEN or COS onward connections are on SkyWest-operated aircraft. SkyWest Airlines buckled under cascading network pressure on June 18, 2026, with SkyWest recording among the highest cancellation counts at O’Hare today.
SkyWest’s COS operation is anchored on the COS–DEN–onward United connection — the route that feeds Colorado Springs passengers into United’s Denver hub for connections to Houston, Los Angeles, San Francisco, Chicago, New York, and international destinations. When SkyWest cannot position an aircraft into COS because of the national cascade, every passenger booked on a COS–DEN United Express service today faces cancellation.
The specific cruelty of the SkyWest cascade at COS: SkyWest operates thin-frequency routes here — often a single daily round-trip on each COS service. A cancellation is not a delay. There is no next SkyWest COS–DEN service this afternoon. The next service is tomorrow. Passengers who needed to connect at Denver today — for a United international departure, for an onward domestic leg, for a meeting in Houston — are stranded for 24 hours.
SkyWest/United passenger action: Your booking is with United. Contact United at united.com → My Trips or call 1-800-864-8331. United’s active Midwest waiver covers rebooking through June 20 — if the COS disruption qualifies under that waiver, you can move to June 19 or June 20 at no charge. United is responsible for rebooking your entire itinerary, including any onward connections you were supposed to make at Denver.
American Airlines operates COS routes to Dallas-Fort Worth (DFW) and Chicago O’Hare (ORD). Both destinations are in the disruption zone today — DFW is recording elevated delays as a downstream effect of the national weather cascade, and ORD is the epicentre of today’s crisis with 207 cancellations. American COS passengers flying toward Chicago today face the worst possible compound: their COS–ORD service may arrive into an O’Hare that is itself chaos.
For COS → ORD American passengers specifically: If your American COS–ORD flight operates today and arrives at O’Hare, you are landing into an airport with 1,425 total disruptions. Your onward connection from O’Hare — if you have one — is at extremely high risk. Contact American before boarding at COS to flag your onward connection. American’s gate agents can sometimes pre-rebook a connection that is at risk before you board the inbound leg, saving you the queue at O’Hare’s Terminal 3 on arrival.
American passenger action: aa.com → Travel Notices for active ORD waiver. 1-800-433-7300.
Delta operates COS to Salt Lake City (SLC) and Atlanta (ATL). Salt Lake City is not in the primary disruption zone today. Atlanta is recording elevated disruption as a downstream effect of the June 15 Day 76 positioning debt. Delta COS passengers should check their flight status at delta.com → Manage Trip.
Allegiant operates seasonal leisure routes from COS to Phoenix and Santa Ana. Allegiant’s lean model — no same-day rebooking, no hub connections — means Allegiant COS passengers facing cancellations today have fewer recovery options than passengers on legacy carriers. Check allegiantair.com → My Trips.
For passengers whose COS flight to Denver has been cancelled today, the most practical option is not rebooking a flight. It is driving.
Denver International Airport is 75 miles north of Colorado Springs via I-25 North and E-470 East — a drive of approximately 60–80 minutes in normal traffic. Denver city centre is 65 miles north — approximately 55–70 minutes.
This is the COS disruption day reality: the airport exists to save you the drive to Denver. When it cannot do that job, the drive to Denver is exactly what you should do.
Driving options from Colorado Springs to Denver Airport (DEN):
Own vehicle or rental car: The fastest and most flexible option. I-25 North from Colorado Springs runs directly to the E-470 beltway, which connects to DEN’s Pena Boulevard entrance. Rental cars are available at the COS terminal from Enterprise, Hertz, Budget, and Avis — call ahead to confirm availability before assuming a vehicle is available on a high-demand disruption day.
Groome Transportation (Colorado Springs → DEN): Groome operates a dedicated shuttle between Colorado Springs and Denver Airport. Departures run every 2 hours from multiple Colorado Springs pickup points. Fare: approximately $39 each way. Book at groometransportation.com or call 719-687-3456. On high-disruption days, Groome vehicles fill quickly — book online immediately if this is your chosen option.
CDOT/Bustang Interregional Express: Colorado Department of Transportation’s Bustang bus service operates Colorado Springs to Denver Union Station (not DIA directly). From Denver Union Station, the University of Colorado A Line train connects to DEN in approximately 37 minutes. Bustang fare: approximately $8. A Line fare: approximately $10.50. Total cost: ~$18.50 each way, total journey 2.5–3 hours. Slower but cheapest option.
Uber/Lyft COS to DEN: A rideshare from Colorado Springs to Denver Airport is approximately $80–$120 depending on surge pricing. On a major disruption day when every COS passenger is simultaneously trying to reach Denver by road, expect significant surge pricing. Hailing now — before the post-cancellation queue forms — reduces your surge exposure.
Once you reach Denver Airport: Denver is also disrupted today. Southwest cancelled 4 aircraft at Denver with ripple effects producing over 200 delays across North America. Arriving at DEN does not guarantee a clean onward connection. Check your specific Denver onward flight status before making the drive — if your DEN–ORD connection is also cancelled, driving to Denver only to find O’Hare has cancelled your flight is not a solution. Call your airline before you leave COS.
This is the most important section for passengers who were booked on a COS–ORD or COS–DEN–ORD connection today.
Chicago O’Hare has recorded 207 cancellations and 1,218 delays on June 18 — the same day your Colorado Springs flight cancelled. Your COS flight cancellation and your ORD chaos are not two separate problems. They are the same problem, manifesting at two points on the same itinerary.
If you rebook your COS flight to tomorrow — June 19 — and your ORD onward connection was also cancelled today, you face a 24-hour rebooking queue at both ends simultaneously. The right action is to contact your airline now and rebook the entire itinerary — not just the COS leg — for the next viable date.
What to ask when you call:
“My COS departure has been cancelled. My onward connection at ORD has also been cancelled. I need the entire itinerary — COS to my final destination — rebooked on the next viable date. Please do not rebook the COS leg only.”
This framing forces the airline to treat your disruption as a single end-to-end rebooking problem rather than two separate legs that happen to connect. It is your right under DOT rules to be rebooked to your final destination, not just to the next intermediate point.
Every cancellation at Colorado Springs today — regardless of whether it was caused by O’Hare’s weather, Southwest’s positioning failure, or SkyWest’s cascade — entitles you to an unconditional full cash refund to your original payment method within 7 business days for credit cards.
The DOT’s 2024 Final Rule requires airlines to process these refunds automatically, without passengers having to request them. If your airline offers a travel credit or voucher as a substitute — you are entitled to decline and request the cash refund.
You are entitled to rebooking on the next available flight to your final destination at no additional charge. This includes:
From 2+ hours of delay at the airport, you are entitled to meals and refreshments. At Colorado Springs — a small terminal with limited dining options — this may take the form of a meal voucher redeemable at the airport’s food outlets, or a cash equivalent. Ask at your airline’s desk or gate.
Today’s COS cancellations are attributed to the cascade from the Chicago thunderstorm GDP. Airlines will classify these as weather-related extraordinary circumstances and decline DOT cash compensation for the initial cause. However, if your specific flight’s cancellation was caused by a positioning failure — an aircraft that failed to arrive not because of active weather at COS but because of a scheduling or crew failure originating at another hub — the extraordinary circumstances defence weakens. Document the stated cause in writing at the COS gate desk before leaving the terminal.
| Metric | Normal COS day | June 18, 2026 |
|---|---|---|
| Daily departures | ~40 | ~36 (4 cancelled) |
| Cancellation rate | <1% | ~10% |
| Airlines cancelling | Typically 0 | Southwest + SkyWest |
| Routes severed | 0 | Denver · Dallas · Chicago · Phoenix |
| Passengers stranded | ~0 | Est. 200–400 |
| Media coverage | None | FlightAware flagged nationally |
A 10% cancellation rate at a 40-departure airport is proportionally identical to the cancellation rate at O’Hare today (207 cancellations from ~2,700 operations = approximately 7.7%). COS is not having a worse day than O’Hare in percentage terms — but the absolute number of stranded passengers is smaller, the recovery options are fewer, and the alternative transport picture (driving to Denver) is the one saving grace that O’Hare does not have.
Tonight (June 18): If your flight was cancelled and you did not rebook today, contact your airline tonight by phone or app. Do not wait until tomorrow morning — rebooking inventory for June 19 COS flights will fill tonight as all today’s cancelled passengers compete for tomorrow’s seats.
Tomorrow (June 19): Day 80 of the US aviation crisis. O’Hare’s positioning debt from today’s 1,425 disruptions will be active. SkyWest and Southwest will be running reduced staffing as crews recover from today’s cascade. June 19 at COS will be better than June 18 — but it will not be a normal day.
June 26 (Italy strike): Not a COS concern directly — but passengers whose onward COS–DEN–ORD–Rome or COS–DAL–MXP itineraries involve Italian airports on June 26 should note that Italy’s nationwide ground-handling strike is confirmed and carries no protected service windows.
