U.S. Airlines Raise Domestic Fares Despite Lower Fuel Prices

U.S. airlines are raising base fares on many domestic flights even though they are getting a windfall from lower fuel prices. Delta Air Lines raised fares on many U.S. routes by $4 per roundtrip last Thursday. FareCompare.com CEO Rick Seaney and J.P. Morgan analyst Jamie Baker say other big airlines have matched them. Seaney says he's seen a few $6 and $10 increases, but most of them were for $4. Delta Airlines did not comment. United Airlines has confirmed matching the $4 increase. Seaney said American and Southwest also have raised prices.
