We use our (My) points and miles regularly, so I am not really saving for some big huge trip. Among our recent trips:

July 1997 -- Trip for 4 to Seattle, using 2 FF tickets, and a free companion ticket I got by signing up for the Citibank AAdvantage card (which I then cancelled after the flight). I paid for my ticket for the miles.

Nov. 97 -- Trip for 4 to Maui on Delta, using 3 FF tickets (and I paid for mine, for the miles).

March 98 -- 1 ticket on TWA for guys' ski trip to SLC to go to Deer Valley with my buddies.

Sept. 98 -- trip to Chicago for 2 on FF tickets.

April 99 -- trip for 4 to ABQ and then Santa Fe for spring break (trip report in trip forum). 3 FF tickets, and I paid for mine to get the miles.

coming soon -- Nov. 99 -- Trip for 4 to Grand Cayman for a week, using 4 FF tickets with combined AA and US miles, and using a combination of AA and US flights, thanks to the new alliance.

That's exactly why I get the miles, and what I like to use them for.
