America West Airlines, US Airways or United Airlines?

Q: Wanting to fly one way from SFO to LAS in January. Have done a few searches (Expedia, Orbitz, etc) and the prices are very similar (if not the same) between America West Airlines, US Airways and United Airlines. Which is the better airline out of the three to fly with? Do any include meals or do you have to pay on each airline (especially America West Airlines)? Any advise would be greatly appreciated.

A:Go with the airline that offers the lowest price for the time you want to fly. Consider buying a round trip ticket and discarding the return portion because it will almost certainly be cheaper than buying a one way ticket.
