I'm looking for an airfare website that has several booking choices. I really like IgoUgo but it doesn't have the one-way flight option.

And although bookingbuddy has that feature, you have to select each airfare site individually, whereas IgoUgo processes numerous choices automatically.

Are there any that fit the above criteria that you know of?

Have you tried www.kayak.com?

Ty, filmwill. Yes, I often select it as a choice when using bookingbuddy.

A couple of other ones:
http://www.airgorilla.com/Engine/Itinerary.asp
http://www.vayama.com/

Try B/T store. Booked one way from Houston to Barcelona for $335 pp. Great people to work with.

Have you tried http://matrix.itasoftware.com ? You cannot book from the site but it gives you all the info you need to book with the airline or via a travel agent. If you are looking for consolidator fares, though, this is not the place

what is b/t store?

volfan_vb,
It stands for the Best Travel Store:
http://www.bt-store.com/default.asp?...&PageID=10

Have you tried Momondo.com, yapta.com or farecast.live.com?

American Airlines will no longer be listed on Kayak as of Aug. 1. It has to do with Kayak results sending people to Orbitz for AA bookings, with the result that AA is charged fees by both Kayak and Orbitz. Other search sites, like Mobissimo and Yapta, don't do this.

Thank you all for your suggestions. I added several of these sites to my Favorites.

Just tried AirGorilla. Very high prices.

I have used BT travelstore for the last few years but this year there prices on the Europe flights I want are not competitive with other sites.
