Best cheap flights web site

Hi, any suggestions on a web site where I may find cheap return flights in either March or April for a week or so ?

I don't have any restrictions so I'm looking for a web site that I can see the cheapest deals for the whole of March and April any suggestions would be welcome

We just want to go somewhere that is warmer than here

I have checked a few:- mommo, travelsupermarket etc and they all want to know where you want to fly from and to. It might be better to go to a Travel Agent and ask them what cheap deals they have on and to where; otherwise try Lastminute.com and see what they have that you fancy, Venice is nice this time of year.

Thanks, that's more or less what I have been finding, you need to pose a date for your travel, the problem is that it can be cheaper even later that day or the day before or the day after.

Will keep on looking

Thanks

Brian
