I bid adieu today as well. It was a good run, and I think I took advantage of all perqs other than a hotel during weather delays (I didn't have any overnight delays). I land at 1P, where I have been for the recent past, having both paid more and flown more in 2010 than I did in earning 1K in 2009.
I will miss:
1. SWUs (my highlight was clearing MEL-LAX-LHR with one SWU)
2. Pretty darn good rate of UDU
3. Great 1K phone service
4. Healthy 1K CS compensation
5. NY/Free award changes
Alas, I never actually received a card, so I don't have anything to frame!
