DALLAS: If you’re planning a big vacation trip this summer, move over. You’re going to have lots of company.

By air or car, traveler numbers are expected to rise over last year thanks to a decent economy and stable gasoline prices.

U.S. airlines expect to carry 234 million passengers from June 1 through Aug. 31, up from the summer record of 225 million a year ago, according to the trade group Airlines for America.

While fares are edging up overall, they are still relatively affordable by historical standards. And travelers can find deals, especially on routes flown by discount airlines such as Spirit.

Some of the lowest fares on popular routes are coming from United Airlines, which is trying to regain passengers lost to rivals in recent years and to overcome the image, replayed over and over on the news, of a passenger being brutally dragged off a United Express plane.

“I call them the mea culpa fares,” says George Hobica, founder of airfarewatchdog.com.

United recently offered $79 round-trip tickets for Chicago-Los Angeles.
