Here’s the List of 40 Airports Expected to Be Impacted by Shutdown Flight Reductions

Starting Friday, the Federal Aviation Administration will cancel about 10 percent of flights at 40 major airports due to a government shutdown that has become the longest in history.

The airports were not previously specified, but there is now a preliminary list that is subject to change, according to The Hill. The full list will be confirmed later today by the Federal Aviation Administration.

Below is the initial reported list:

1. Anchorage International (ANC)
2. Hartsfield-Jackson Atlanta International Airport (ATL)
3. Boston Logan International (BOS)
4. Baltimore/Washington International Airport (BWI)
5. Charlotte Douglas International Airport (CLT)
6. Cincinnati/Northern Kentucky International (CVG)
7. Dallas Love (DAL)
8. Ronald Reagan Washington National (DCA)
9. Denver International (DEN)
10. Dallas/Fort Worth International (DFW)
11. Detroit Metropolitan Wayne District (DTW)
12. Newark Liberty International (EWR)
13. Fort Lauderdale/Hollywood International (FLL)
14. Honolulu International (HNL)
15. Houston Hobbyists (HOU)
16. Washington Dulles International (IAD)
17. George Bush Houston InterContinental Hotel (IAH)
18. Indianapolis International (IND)
19. New York John F. Kennedy International Airport (JFK)

28. Auckland International (OAK)
29. Ontario International (ONT)
30. Chicago O’Hare International Airport (ORD)
31. Portland International (PDX)
32. Philadelphia International Airport (PHL)
33. Phoenix Sky Harbor International (PHX)
34. San Diego International Airport (SAN)
35. Louisville International Airport (SDF)
36. Seattle/Tacoma International Airport (SEA)
37. San Francisco International Airport (SFO)
38. Salt Lake City International (SLC)
39. Teterboro (TEB)
40. Tampa International (TPA)

The cancellation of flights at each of these airports aims to reduce the burden of the closure on air travel safety personnel, specifically air traffic controllers.

Air traffic controllers are essential to safe air travel, but they currently work long hours without pay. According to the National Air Traffic Controllers Association (NATCA), air traffic controllers work mandatory overtime, logging 10 hours a day, six days a week. Moreover, in the absence of salaries, many resort to additional work to make up for the loss. That has caused many air traffic controllers and other federal workers, such as TSA agents, to call in sick or take a second job, adding further pressure to an already strained system.

“A system under stress must slow down,” Delta Air Lines wrote in a statement to congress calling for an end to the shutdown.

Flights to and from the US are already facing major delays, and Transport Minister Sean Duffy warned of more “mass chaos” at a press conference earlier this week.

It is currently unclear exactly what flights will be affected, but it will undoubtedly be a transportation disaster for some travellers, with cancellations likely to have a ripple effect. The Associated Press reported that as many as 1,800 flights and more than 268,000 seats could be affected.

Cancellation decisions, according to Duffy, will be based on reducing pressure on air traffic controllers to avoid any catastrophic errors.

United Airlines said in a statement Wednesday that it will make rolling updates to its flight schedule and give customers several days’ advance notice of any cancellations. United will focus all cancellations on domestic flights, with long-haul international flights or hub-to-hub flights not affected by the cuts. United’s hubs are Chicago, Denver, Guam, Houston, Los Angeles, Newark, San Francisco, and Washington, D.C

“We expect the vast majority of customer flights to continue as planned, and we will proactively reach out to affected customers as schedule changes are made,” American Airlines said in an X post on Wednesday.

United said any customers on grounded flights are eligible for a refund, even if their flight was not cancelled.
