My suggestion would be to use farecompare.com or tripadvisor.com or some such thing where you can get a peek at historical data and/or a list of prices for various airlines. In the current economy, booking in advance doesn't necessarily mean saving money.

Another suggestion would be to spend a few minutes reading the rules of FT:

You've got the same message posted in three different places, which is a no-no.

Welcome to FT and happy flying!
