Same here. Last year was my first year as 1K, and I was not only able to use my SWUs to get Business on LAX-IAD-FCO and return this past week I used paper SWUs to help a friend upgrade on Lufthansa.
90% of my domestic travel I won't miss the upgrades (LOTS of LAX-SFO), hopefully the customer service at lower levels is good again but I felt like as a 1k they really took care of you.
Anyway yeah upgrades are nice though for the long flights. Guess I need to go back to the miles for that (oh and the mileage bonus... stupid 2p... :-/... hopefully I make 1k again next year? probably not likely with the new 120 segment requirement).
Just some of the other things too that require fees at lower levels (specifically stand by... that is going to absolutely KILL me next fall :-/).
Oh well, it was fun while it lasted, maybe one day I'll do it again?
