Umm, I am not so sure it will keep everything. By that, I mean, I had inadvertently changed the schedules way back, where I deleted schedules and then uploaded the newer ones. It shows the schedule still, but the aircraft type just came up as:
Departure Airport: Denver International Airport (KDEN)
Arrival Airport: Toronto Pearson Int'L. Ont. (CYYZ)
Aircraft: ()
Flight Time: 03.02
Date Submitted: 06/08/2010
Route: KDEN MCK J44 LNK DSM OBK ECK V216 YWT CYYZ
Status: Accepted
So, if you are tracking a particular aircraft's hours or something, I am not sure if that gets affected ot not?! Has anyone else ever had that happen with the aircraft listed?!
