What are some good sites/airlines for cheap flights from US to UK?

Im Canadian (Toronto) and I have to fly to England this May.

The flights are rather expensive and Ive paid almost $1000 CDN for them before.These were direct flights.



Im willing to go to Buffalo, NY and catch a flight to England from there and if the price difference is substantial, Im fine with connections as well.



Im wondering what are some really good discount websites for flights to England from US or Canada.

And even better: discount airlines if there are any.



Thanks.What are some good sites/airlines for cheap flights from US to UK?

Currently, I haven't found the discount sites to be any cheaper than buying directly from the airline. I just booked a flight from California to England in June and the cheapest I could find anywhere was $1400 (U.S. dollars including taxes) and that was directly through Virgin Atlantic. Good luck, flights to the UK seem pretty expensive right now, but if you can fly from the east coast you probably have a much better chance of finding something cheaper. Just keep looking!What are some good sites/airlines for cheap flights from US to UK?
