Travelers determined to have a vacation — within a budget

Money may be tight, but not enough for most of us to forgo a summer vacation.

A recent survey by travel site Orbitz.com found that nearly eight of 10 respondents will be taking a vacation this summer. Some plan to spend more than last year, but nearly half of the 750 people polled vow to keep their travel budget under $1,500.

"They don't have a set destination in mind but say, 'Where can we go that fits within our budget?'" says Jeanenne Tornatore, senior editor at Orbitz.com.

Tornatore says that probably explains why — with airfares up — the top 10 destinations for the summer are all in the United States except one — Cancun, Mexico.

Budget-conscious travelers will be able to find deals, but it won't be easy.

"This summer is about getting a better bad deal," says Rick Seaney, CEO of FareCompare.com. "The deals will be few and far between, so don't procrastinate."

Here are some tips:

Expect higher airfares: Rising fuel prices, growing consumer demand and fewer seats because of airline consolidation have pushed airfares higher.

Domestic flights cost 6 percent or so more than a year ago, and international flights have risen more than that, travel experts say.

George Hobica, founder of Airfarewatchdog.com, says airlines can change fares many times during the day, so he recommends setting up fare alerts at one of the online travel sites to notify you by email or Twitter when prices fall.

Plenty of travel sites allow you to compare airfares among airlines. But check airlines' sites as well because they may post even cheaper fares, Hobica says.

"They just want to keep the business to themselves," he says. "They don't want to pay commissions to online travel agencies."

If you are booking far in advance and worry that you might miss out on a lower fare later, consider flying with JetBlue, Southwest Airlines or Alaska Airlines, Hobica says. They will allow you to switch without penalty to another one of their flights if the fare is lower, he says. Plus, they will give you a credit that can be used for future travel, he says.

Break up a trip: You pay about 20 percent more for a nonstop flight, so it's cheaper to use connecting flights, Seaney says.

You also can save money by taking a less direct route or using more than one airline.

For instance, Hobica says a round-trip fare from Dallas to Honolulu can cost $500 more than from Houston to the Hawaii capital. It would be cheaper to get a flight from Dallas to Houston, and then hop a plane to Honolulu, he says.

Similarly, you can save hundreds of dollars by flying from New York to Berlin and then to Paris, rather than going directly from New York to Paris, Hobica says.

"You have to leave plenty of time between connecting flights," he warns.

Most travelers book round-trip tickets with one airline to get more frequent-flier miles or other perks. But travel experts say that it can be cheaper to fly with one airline to your destination and take another carrier back home.

Timing is everything: Cut costs by avoiding peak travel times. Seaney advises scheduling airline departures and returns for the least expensive days — Tuesdays, Wednesdays and Saturdays. Early-morning and evening flights tend to be cheaper, too, he says.
