i don't follow sometimes...

(don't take this the wrong way - an upgrade to the front is a big bonus for me --- i'm not looking a gift horse in the mouth here...)


my flight tomorrow:

Flight 1144 : Salt Lake City, UT to Washington (Reagan National), DC on 20 Oct 2009



xxxxxxxxxxxxxmy name here #9 of 21 on Upgrade List

Current Seat Availability Seat Availability First Coach
Total Available Seats 18 13




what is the logic behind these upgrades not processing at the usual 5 day out for plats?

again, just trying to understand the logic --- i might change my flight patters if i can better understand how the process works



TIA
