I like the airlines that give you credit when the price goes down (if it goes down). So, Southwest, Alaska, Jet Blue... I believe I booked our flights in June. The prices were decent to me, though my wallet squeaked a bit, LOL. But I have a background of flying in the very early 80s and it was FAR more expensive then that it is now...so I know it could be WAY worse, and try to be realistic (do we even pay for the fuel when we pay $100 per person each way? that sort of thing). Anyway, I saw prices that I could deal with on flights I figured I would be comfy on, and booked. And then I checked obsessively to see if the prices went down.
That's my advice. Kayak.com is good, but it doesn't include Southwest. Gotta check SW on their own.
Oh, and if you want to experience the BEST airline (for coach, at least, domestically), and don't mind baggage fees, a weird mileage plan, and no credit if the price goes down, check out Virgin America. I'm going to try to go with them next time, unless we have enough miles to fly all of us on something else, because VA is just SO awesome.
