Southwest Airlines has applied for approval to fly nonstop between Harry Reid International Airport and heavily restricted Ronald Reagan Washington National Airport in Washington D.C.

The Dallas-based commercial air carrier, the busiest airline at Reid International, is seeking one of five round-trip flight slots permitted in the FAA Reauthorization Act of 2024.

Reagan National is restricted by a 1,250-mile perimeter rule that limits the number of flights to the airport from beyond that distance. There are 40 flights that have exemptions to the rule and the new reauthorization adds five round trips to that total.

Currently, only American Airlines offers daily nonstop round trips between Reid and Reagan National.
