When are people going to stop solving this problem and start building super sonic airplanes like the concord? The airline industry moves backwards in technology and trying to build a flight search engine to wrap around it is really a band-aid to the real situation. If I could get to Vegas in half the time, or even a quarter of the time (currently takes 4 hours, could take 1 in supersonic jet) I would pay at least double price for a ticket, and I wouldnt even need a seat. My point is if you fly coach especially with Delta they treat you like a slave and stuff you with almost zero space to move (I am american, but not obese (5'9, 200lb). Forget flight search engines I can find a flight, make a me a faster more tolerable flight, you are friggin GOOGLE!
