Can anyone point me to a website which allows a search for flites within Europe?

The sites I am familiar with, such as sidestep, travelocity, orbitz, etc, all seem to require that at least one US airport be involved, going or coming. But I'm looking for info on flites within Europe. Preferably, a site which searches thru many airlines, not just a single-airline search site.

Thanks, guys.

This site is a bit awkward but's it's a pretty comprehensive for inter-European discount airlines.

Seems Expensive to me for example say I wanted to do a round trip :)

Starting off in the UK going to Amsterdam for a few days then after that going to Lisbon for a few nights then back home to the UK!

So the UK to Amsterdam thats cheap but Amsterdam to Lisbon seems bloody expensive! It would be cheaper for me to go back to the UK and then Fly from the UK to Lisbon instead of going directly from Amsterdam!! What the hell happened there Unless there other airlines that I dont know about!

Travelocity.co.uk.

Thanks, everyone. All of the suggestions seem to work fine. Much appreciated.
