I have only used Travelocity before and found a good deal. I have not tried Priceline.

Which one do you prefer for international airfare?

I have a friend who is from another country but lives here in the States and she really likes qixo.com for international flights.

With any flight, I generally look at travelocity, orbitz, priceline, expedia, and Kayak - and then I check with the airline itself. If the airline's fare is the same, I try to book directly through them. I have this superstitious belief that I'm less likely to get bumped that way.

Also, we have a good ticket wholesaler - consolidator and she saved me a lot of money by booking my flight to Turkey as two seperate flights: 1 to France and a seperate flight from France to Turkey.

I would probably not use priceline's name your own price feature for international flights. My vacation time is precious enough that I wouldn't want to be stuck with bad flight times, or a layover.

Then again, those are certainly not your only two choices. Travelocity is one good research tool, but many sites offer good fare searches. Ultimately, you can often get the best price by finding flights this way and then booking through the airline directly. But not always - sometimes the online travel agents like travelocity offer a sale fare that you cannot find on the airline's own site (but maybe could if you called?).

It comes down to how much time you have to spend researching the best fares, and how much the money means to you (vs. getting a slightly higher fare more quickly).

I would never use Priceline for international flights, except for the rare case when I needed last min flights and was doing a definite non-stop, single leg flight, like JFK - LHR.

Come to think of it, same probably holds true for domestic flights as well. I have strong preferences for total travel time and routings.

I do use PL all the time for hotels, and always consult biddingfortravel.com beforehand.

I use priceline for hotels & rental cars only. I did use them for airfare for a trip to Ireland about 5-6 years ago. There were at the time only about 2-3 airlines that flew from Newark to Shannon, so I figured I didn't have anything to lose.

They booked me on Continental. The only problem was the bid price didn't include taxes/fees, so if you have an idea what they are, no problem.

As for travelocity, orbitz, expedia, and the like, I only use them to find out what airlines are going my way, then call the airlines direct to book or go on line to book. Saves you the $25-30 fee the travel sites charge you.

I like Travelocity for Total Trip deals.
I have saved a ton on combining hotel and air.

Have a look at the Priceline packages. With these, you can pick hotel and flights. I got some amazing deals for London last year and the year before.

I would not Priceline for airfare only (prefer direct flights and convenient times). But, I wouldn's use Travelocity either.

This year, I've had great luck with 1800flyeurope

Priceline has a regular booking option, too, doesn't it? I haven't found any good deals on Travelocity lately. i booked my International flight through AA though they were not the carrier! Funny, but they were 200 dollars cheaper than the airline which I booked. A good place to start is sidestep.com Also, if you want side-by-side comparisons on hotels, etc, go to tripadvisor.com
