There will be five new round-trip flights each day at lawmakers’ favorite airport, thanks to a major aviation bill that passed the House on Wednesday and will soon be signed into law by President Joe Biden. Now a major question remains: Which destination cities will be chosen?

The campaign to add more flights at Reagan National Airport, known as DCA, has been simmering for over a year, and now, it’s up to the airlines to put applications in to the Department of Transportation over the next 60 days. From there, the agency will evaluate and ultimately determine which airlines and cities will be granted the additional flights.
