DALLAS >> Enjoy lower airfares while you can. Airlines are taking steps to push prices higher by next year.
Fares have been dropping for more than a year. Taking inflation into account, the average round trip within the U.S. in late 2015 was the lowest since 2010.
Ticket prices have fallen even further this year, according to the airlines. Not only is flying from Dallas to Denver cheap, but popular international vacation destinations like Europe are more affordable.
Fliers can thank the steep plunge in oil prices since mid-2014. As they saved billions of dollars on jet fuel, both domestic and international carriers added supply — seats — faster than travel demand was growing. The major airlines have announced steps to rein in the oversupply, but such changes can't happen overnight, so fares will remain affordable for the peak travel season.
One downside: Be prepared to spend a few more hours of your vacation standing in an airport security line.
Expect more passengers
The number of airline passengers this summer is expected to rise 4 percent over last year's record level. That, along with fewer Transportation Security Administration screeners, is expected to create long lines.
American Airlines and United Airlines say they each plan to spend about $4 million on contractors who will help TSA by handling some of the non-screening duties at airport checkpoints, like running bins and managing the lines.
Stories about horrific lines might be an opportunity for last-minute deals, according to Pauline Frommer, editorial director of the travel guide company Frommer's.
"If American Airlines is going to spend $4 million of its own money, obviously the airlines are nervous about not being able to sell last-minute seats," she said. "I wonder if this rash of bad publicity won't make getting a last-minute booking more affordable."
Signing up for fare alerts from the airlines and price-tracking websites can help consumers spot those deals, many of which lapse quickly.
Last week the price-tracking website airfarewatchdog.com spotted $688 round trips on British Airways and American leaving New York on July 6 and returning July 17. George Hobica, the site's founder, said $1,200 would be more typical for peak season. The sale was gone after one day.
If you don't have kids in school, the easiest way to save money would be delaying a big trip until at least mid-August. "After that, we see fares drop off a cliff," Hobica said.
Within the U.S., the cost of an average round trip fell about 8 percent last year to $363, according to government figures. Through March, the average fare per mile was down 6 percent from early 2015, according to the industry trade group Airlines for America. Fares have fallen faster on international routes than on domestic ones, largely because the foreign airlines added of a glut of flights.
U.S. airlines now get about $1.1 billion more from baggage and ticket-change fees.
