You asked for tips. Tips on using FT? Or mileage earnings tips?

For the latter, just lurk around the forum of your choice (United, Continental, or whatever) and you'll very quickly see some tips.

And actually, that would be my answer to the first question as well. As I'm sure you're aware from other Internet boards, lurking and observing are often the best way to get a pulse on a new place. And if you have something to add, jump right in.

Enjoy!
