Suggestions for websites, airlines for cheap one-way tickets US to UK, please

I've been checking this site:   http://www.bt-store.com
and getting good prices for one-way, mostly always with BMI, but it's the only site I know and would like more suggestions.

This was recommended to me by another friend.  http://www.skyscanner.net/  Hope it helps!

I don't understand that site, lissy.  After I click on my departure airport (Philadelphia International) it only gives me a choice of Mexico or the Dominican Republic for my destination. 

Edited:  I see now--I have to fly out of NYC!  But one-way doesn't seem to be an option...

I got a good one way using www.1800flyeurope.com. It doesn't show the airline until you've bought the ticket but it easy enough to figure it out using Expedia or Orbitz.

I like www.sidestep.com.  I've been able to get some good deals off of that site.

i use kayak.com (or kayak.co.uk).

it searches a bunch of sites for the best fares, and there is a one-way option if you register (free and very simple). you then follow a link to the airline's site, where you actually do the booking.

Good luck finding a cheap one-way.  When I was looking for a ticket to move here, one-ways were MORE expensive than returns!

I like expedia.com.  Good customer service.

I always use www.cheaptickets.com

Thanks everyone--I will check out all of those links.

Yael--I know that *normally* one-way tix are more expensive than round-trip, but sites like the one I mentioned get you good deals with one-way travel though they are the exception.

Airgorilla.

it searches most of those previously mentioned all at once.
