(The Hill) — In response to the historic government shutdown, several airlines are now providing refunds and complimentary flight adjustments for travelers facing disruptions due to newly imposed restrictions.

On Wednesday, Federal Aviation Administration (FAA) chief Bryan Bedford announced that starting Friday morning, the agency will decrease the capacity by 10 percent at 40 major airports across the nation. This decision is a result of the ongoing staffing shortages among air traffic controllers affecting facilities countrywide.

Following the FAA’s directive, United Airlines is set to reduce its daily flights by 4 percent throughout the weekend, according to a spokesperson from NewsNation, a sister outlet of The Hill. The airline assured that they are striving to “minimize disruption for our customers and crews.”

United CEO Scott Kirby, in a message on the company’s website, assured passengers that they would receive “several days’ advance notice” of any flight alterations. He further stated that United intends to spare its long-haul international and hub-to-hub flights from reductions, concentrating instead on cutting “regional flying and domestic mainline flights that do not connect our hubs.”

Kirby also highlighted that any passenger opting not to travel under the current restrictions, even if their flights remain unaffected, will be entitled to a refund.

Similarly, American Airlines announced on Thursday that it anticipates the “vast majority of our customers’ travel will be unaffected,” with long-haul international flights maintaining their schedules. Moreover, the airline committed to refunding customers whose flights are canceled “for any reason” and allows travelers to change their flights or request a refund without incurring penalties.

Delta Air Lines also expressed confidence that most of its customers’ travel plans, including long-haul international flights, will not be impacted by the restrictions. In a release, Delta said that all customers traveling to, from or through the impacted markets while the capacity limits are in place may change, cancel or refund their flights without penalty. 

Bedford, during a press conference alongside Transportation Secretary Sean Duffy, cited the need to “take the pressure off of” air traffic controllers, who are set to miss their second consecutive paycheck on Tuesday amid the record-long government shutdown. 

So far Thursday, over 3,300 flights within, into or out of the U.S. have been delayed, with at least 68 such flights cancelled, according to the flight-tracking site FlightAware. It is unclear what percentage of those flights were disrupted due to controller staffing shortages.

The FAA is expected to announce the airports impacted by the restrictions later Thursday, while a preliminary list was obtained by NewsNation.
