DALLAS -- Major U.S. airlines are again trying to raise prices on many domestic flights.
Delta Air Lines Inc. confirmed Friday it had raised fares to Florida, Phoenix, and Las Vegas by up to $10 per round trip. JetBlue Airways Corp. said it raised fares on many U.S. routes by $6 per round trip, and US Airways Group Inc. said it matched JetBlue.
The fare hikes indicated airlines are still seeing strong demand for travel despite the weak economy. Airlines have imposed about 10 broad fare increases this year, but an equal number have failed because some carriers declined to go along with higher prices.
