United and Continental are raising airfares on many U.S. routes by up to $20 per round trip ticket. It's the latest effort to cover spiraling fuel costs across the airline industry.
The two airlines raised prices Thursday night. Spokesman Mike Trevino says fares went up $3 each way on flights longer than 500 miles, and $10 each way for first-class tickets.
U.S. airlines have raised prices more than a half dozen times this year. Most still lost money in the first quarter due to higher fuel costs. United Continental Holdings Inc. lost $213 million. Its fuel bill rose $560 million, or 26 percent from a year ago.
