Delta Air Lines has achieved partial success in lobbying the federal government to approve new 'beyond perimeter' slots at Washington's National Airport. Currently, flights at the airport are capped and assigned to specific airlines, with no flights permitted beyond 1,250 miles without an exemption slot.
Delta sought 28 new roundtrips a day from Congress but faced significant pushback, particularly from United Airlines, which has a hub at Dulles and aims to maintain its semi-monopoly on long-distance flights in the region. Ultimately, Congress added five roundtrips per day: four for the largest airline and one for an airline with an existing presence at the airport.
Now there is competition over which airlines will receive these slots. Delta is working to prevent American Airlines from obtaining one of them by promoting letters to the Department of Transportation (DOT) from labor union SEIU and consumer groups. These letters argue that American Airlines already holds the most beyond-perimeter slots at National Airport.
