Cheapest Flights UK to USA

Hi all,

Having just looked at the ATIflights post after thinking that we were getting the best flights with Orbitz, we were wondering whether we've actually been getting the best flights the other way from the UK to the US.

From experience, which websites have you all found to be the cheapest that way?

Thanks

I've never booked UK to US but I've always used Kayak.com.  Or Priceline.  Naming your own price works great if you don't care about flight times- saved me almost $300 on my last flight.

One thing I'm considering doing is booking a one-way from the UK to the US, then a one way from atiflights from the US back to the UK.
