Boston Logan Is Today’s Worst US Airport: 495 Total Disruptions — 412 Delays, 83 Cancellations, and a 124-Minute Average Ground Delay as Runway Construction Meets Northeast Thunderstorms

No other US airport comes close to Boston Logan’s disruption total today — and the reason is a combination this site has been tracking for two weeks running.

Boston Logan International Airport recorded 412 delays and 83 cancellations today — 495 total disruptions — making it by a wide margin the single most disrupted major airport in the country, according to FlightAware data. The FAA’s own operational logs show average ground delays reaching 124 minutes, more than double what most other affected airports are experiencing today. The cause is the same one this site flagged when Logan’s Runway 9/27 closure began: a planned 75-day safety upgrade installing additional Engineered Materials Arresting System (EMAS) protection, now compounded by convective thunderstorm activity moving through New England today.

Today marks roughly two weeks into the closure, which began August 31 and is scheduled to run until mid-November. With the runway still out of service, Logan simply has less capacity margin than normal to absorb any additional disruption — and today’s thunderstorm cells landed directly on top of that already-reduced baseline, producing the outsized 124-minute average delay figure.

Why Boston Keeps Topping the National Disruption Table

This is now a well-established pattern rather than a one-off event. Every time this site has checked Boston’s status against the rest of the national disruption picture over the past two weeks, Logan has either topped the table or come close to it — a direct consequence of operating with one fewer runway than normal for an extended period. Under normal conditions, an airport can typically absorb an afternoon thunderstorm cell with moderate, temporary delays. With Runway 9/27 closed, Logan’s controllers have meaningfully less flexibility to redistribute traffic around any additional disruption, which is precisely why today’s 124-minute average — more than double what several other affected airports are reporting — tracks so closely with the pattern seen since the closure began.

What JetBlue’s Exposure Looks Like

As Boston’s largest carrier by a significant margin, JetBlue is disproportionately exposed to any Logan-specific disruption, including today’s. The airline operates extensive year-round domestic and transatlantic service from Logan — including its long-established routes to London Heathrow, Amsterdam, and Paris — meaning a bad day at its home hub ripples through both its domestic network and its international connecting banks simultaneously.

Your Complete DOT Rights Guide

✅ Full Refund — Unconditional for Cancellations

Regardless of cause, any of today’s 83 Boston cancellations entitles affected passengers to a full refund to their original payment method if they decline rebooking.

⚠️ DOT Cash Compensation — Unlikely for This Disruption

Both the runway construction and today’s thunderstorm activity are generally classified as outside airline control, similar to weather generally — making the standard DOT-tracked compensation commitment (up to $775 for controllable delays of 3+ hours) unlikely to apply.

✅ Rebooking to Final Destination

Given how many carriers are affected simultaneously at Logan today, ask about rebooking on a partner or competing airline if your own carrier’s next available flight involves an unreasonable wait.

How to File a DOT Complaint

Get the specific stated cause in writing → file directly with the airline first → escalate to airconsumer.dot.gov if unresolved.

What to Do If You’re Flying Through Boston This Week

✅ Build in significant extra buffer time for afternoon flights — this remains a predictable daily pattern through mid-November, not a one-off risk ✅ Check your specific flight status before heading to the airport, particularly if traveling later in the day when delays tend to compound ✅ If your JetBlue flight is affected, ask specifically about rebooking options given the carrier’s dominant Logan presence and correspondingly larger rebooking inventory
