It is better to be stuck at home or in a hotel than to be stranded in an airport terminal, so use the airline’s app or flight websites to make sure that your flight is still on before heading to the airport. This FAA site can be checked to see if there are widespread delays at your airport.

As the federal government shutdown carries through to another day, making it the longest in U.S. history, flight disruptions continue.

The reductions in airspace capacity will start Friday, the 37th day of the shutdown, and just ahead of the busy Thanksgiving travel period.

On Friday, the FAA said nearly half of the 30 busiest U.S. airports faced shortages of air traffic controllers, leading to more than 6,200 flights being delayed and 500 canceled, in the single worst day since the shutdown began.

Austin-Bergstrom International Airport is currently under a ground delay due to staffing, according to the FAA.
