US Airways Group Inc. announced Tuesday it will begin nonstop daily seasonal summer service from Philadelphia to Salt Lake City on May 24.

Additionally, US Airways will add another daily frequency on March 25 between Philadelphia and St Louis, Mo.; Nashville, Tenn., Houston; Albany, N.Y.; Bangor, Maine; and Indianapolis.

Separately, US Airways announced new daily flights at Washington Reagan National airport, where it acquired some takeoff and landing rights from Delta Air Lines.

Philadelphia's dominant carrier will begin flying in March nonstop from Washington to Birmingham, Ala.; Fayetteville, N.C.; Islip, N.Y.; Little Rock, Ark.; Jacksonville, N.C.; Pensacola, Fla.; Tallahassee, Fla.; and Fort Walton Beach, Fla.; Memphis, Tenn.; Omaha, Neb.; Ottawa; Ontario; Bangor, Maine; and Savannah, Ga.

The new schedule at Washington Reagan will be offset by less flying at New York LaGuardia airport, where Delta acquired 132 US Airways slots. US Airways acquired 42 Delta slots, which translate into round-trip flights, along with international rights to fly to Sao Paulo, Brazil, in 2015. Delta will also pay $66.5 million to US Airways.    - Linda Loyd
