TravelThe short answer
- The FAA issued ground stops at nine major airports on August 6 and seven more on August 7, as severe thunderstorms combined with equipment failures and air-traffic-controller absenteeism.
- Cancellations reached nearly 2,000 nationwide by Friday, with Republic, PSA, JetBlue, Endeavor and Delta among the hardest hit.
- Minneapolis-St Paul alone logged 28 cancellations and 413 delays.
- Delta and United waived change fees and fare differences for affected passengers, with rebooking windows extending to August 10 and 11.
A run of severe thunderstorms, combined with equipment outages and gaps in air-traffic-controller staffing, forced the FAA to ground-stop more than a dozen major US airports over two days this month, pushing nationwide cancellations close to 2,000.
Which airports and airlines were hit
- August 6 ground stops: Atlanta, Boston, Baltimore-Washington, Reagan National, Dulles, Las Vegas, LaGuardia, Orlando and Minneapolis-St Paul.
- August 7 ground stops: Reagan National, Newark, Dulles, JFK, LaGuardia, Philadelphia and Teterboro.
- Airlines with the most cancellations on August 7: Republic (373), PSA Airlines (261), JetBlue (245), Endeavor Air (200) and Delta Air Lines (174).
- Minneapolis-St Paul alone recorded 28 cancellations and 413 delays.
What caused it
The immediate trigger was severe thunderstorms moving across the Eastern seaboard and Midwest, but the disruption was compounded by equipment failures at several facilities and higher-than-normal absenteeism among air traffic controllers at several hubs, a combination that turned a weather event into a multi-day, cross-network problem.
What travelers can do
- Check your airline's advisory page directly rather than relying on the departure board; Delta and United have both waived change fees and fare differences for affected itineraries.
- Rebooking windows from the waivers extend to August 10 and 11 on the affected carriers, if you were booked during the disruption.
- Build in extra connection time at the East Coast hubs named above while the backlog clears.
- If your flight was delayed rather than cancelled, you may still be owed duty-of-care assistance depending on the carrier and route; see our guide to air passenger rights.
The honest caveat
Storm-driven, multi-airport disruptions like this recur through peak summer travel and are not fully predictable more than a day or two out. The specific airports and numbers here describe this incident; check your airline directly before assuming similar treatment applies to a later disruption.
