Wow! Thank you EVERYONE for all of the information! I should have said earlier that I am brand spankin' new with US Airways. Actually, orientation starts this week and if anyone has ANY pointers at all on the best way to memorize airport names and codes.....I will send you holiday cards forever

So I don't know if I have access to check flight loads, at least not yet anyway. I do have one question which has really caught my attention. Does ID90 or ID80 (seen various forms) really mean 90% off the base fare, or does it mean 10% or 20% off.

Also, if I fly ID90 am I "guaranteed" a seat just like any other pax?

Depending on the answer, it might benefit me to fly this way with the kids and nonrev when I have more flexibility.

Again, thank you all!!!!!!!!!!!!!!!!
