DALLAS — United Airlines is trying again to raise prices after a similar move failed this month.
United said Wednesday that it raised prices for travel within the United States by up to $20 per round trip.
United Continental Holdings Inc. said it raised prices $2 each way for flights under 500 miles, $3 for 501 to 1,000 miles, $5 for 1,001 to 2,000 miles, and $10 each way for flights longer than 2,000 miles or involving Hawaii or Alaska. United tried to raise prices by up to $10 per round trip on Jan. 3 but rolled back the increase after others, notably Southwest Airlines Co., kept their fares unchanged.
JPMorgan analyst Jamie Baker said he expected some other big airlines to raise prices, too, but that Southwest’s support would be needed for the increase to stick.
Southwest carries more passengers within the United States than any airline and wields great influence over prices on many routes.
