Question

Best site for cheap airplane tickets (cross-country)?

Answer 1

Really i cant say it depends on where you are going and when your going. If you are looking just over all i would say Priceline cause you can name your price. But here is a better way....

Send me an email with the airline and the date and ill find it for you i've been doing this stuff for years ill find it for.

Answer 2

http://www.bookingbuddy.com will check Priceline for you, plus Cheaptickets, Orbitz, Kayak, airlines direct, consolidators, aggregators, site-scrapers, etc. etc. all in 1 go.  

Low-cost airlines such as Southwest do not show up or participate in other booking sites.  You have to check them individually -- http://www.southwest.com
