07:08 AM EST, 12/18/2024 (MT Newswires) -- The US Department of Transportation finalized its award of five new daily round-trip flights from Washington Reagan National Airport to major airlines following legislation signed by President Biden in May, multiple media outlets reported Tuesday.

Reuters said the new flights, set to begin within 90 days, will be operated by American Airlines ( AAL ) , Delta Air Lines ( DAL ) , United Airlines (UAL), Southwest Airlines ( LUV ) , and Alaska Airlines (ALK).

The reports said the routes include a Delta flight to Seattle, a Southwest ( LUV ) flight to Las Vegas, an American Airlines ( AAL ) flight to San Antonio, Texas, an Alaska Airlines flight to San Diego, and a United Airlines flight to San Francisco.

The decision follows tentative awards made in October.

The Transportation Department rejected JetBlue's ( JBLU ) proposal to add a flight to Puerto Rico, according to Reuters.

"Following an approval from the U.S. Department of Transportation, Alaska will soon offer the only nonstop service between San Diego International Airport and Ronald Reagan Washington National Airport," Alaska Airlines said in a statement.

American Airlines ( AAL ), Delta Air Lines ( DAL ), United Airlines, and Southwest Airlines ( LUV ) did not immediately respond to MT Newswires' request for comment.
