US airlines raise base fares on domestic flights

DALLAS (AP) — 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 round on Thursday night. FareCompare.com CEO Rick Seaney and J.P. Morgan analyst Jamie Baker say other big airlines have matched them. Seaney said Monday that he saw a few $6 and $10 increases, but mostly $4.

Delta did not immediately respond for comment. United Airlines confirmed matching the $4 increase. Seaney says American and Southwest also raised prices. The carriers did not immediately comment.
