I have recently uploaded AI flight plans for United Airlines and Alaska Airlines to AVSIM and to my website:
http://www.buckeyediscus.com/fs2002/
These plans are a 7 day schedule for United Airlines and Alaska Airlines. You must have TTools to add this to your traffic.bgl file. (this file was created with real life data downloaded from the Department of Transportation and depicts actual movement of United Airlines and Alaska Airlines by N-number for the week of Feb 1 to Feb 7, 2002).

Exceptions are listed on my website (and in the readme.txt file).


Thanks
