I find that if time is getting short, or I’ve noticed the rates creeping up on a ticket I want, that sometimes Hotwire will still have the lower price available when the other sites (including the airline directly) don’t show it. However, with Hotwire the price you pay for the cheaper tickets is that you don’t know who or when you’re flying out: just the day. (Normally though, I know what airlines serve that city from here, and I know roughly when they fly into that city, so this isn’t a problem for me.)
Keep an eye for package deals. If you know you’ll be needing a car and/or hotel at your destination, there are times when you can save some $$$ this way (but not always). It depends on who’s running promotional deals with each other.
Write down any and all confirmation numbers, and note down whose confirmation number it is. (Is it the airline’s number, the travel agency’s number, etc.)
Other tips/tricks involve doing some reasearch on the flights to the cities you tend to fly into the most. When do the business travellers normally fly there, if they go there at all? Do those other cities serve as hubs for transfers to popular vacation spots, and when do people want to go to those vacation spots? (For instance: if I fly into Charlotte, NC, when I know people are travelling to Florida, my flight will be fuller than normal no matter what time of day/week. But, it doesn’t seem to affect my flights into Atlanta during the same time frame.) Is there something happening in the city you fly to, or in a city that’s served mostly by the hub you are going into? (Super Bowl, major industry confererence, etc., etc.)
I wish I could remember where, but some sites will show a small history for that particular flight: the amount of time it’s ‘on-time’, how full it usually is, etc. That can help with planning transfers.
(And a free-tid bit: AirTran is usually cheap, but they’ve been lousy in my experience for getting me to where I want to be on-time. On the other hand, when they screw up, they’ve always made good.)
Whew. Didn’t mean to write a book there, but…
