Took the 763 on AA a few times -

RDU-LHR/FCO-JFK - First time in NGBC as a 22 year old - thought it was great! (2008-2009 NYE trip)
JFK-MXP - Got op-uped to NGBC (as PLT!) with my now husband, remember the guy next to me was flying to fashion week and slept the whole time. Thought someday I would do the same on a long haul instead of drinking and enjoying - was 23 - still haven't given up the enjoyment and just deal with the lack of sleep. (2010)
FCO-ORD - Coach. No fun, several hours of the Rachel Zoe project made me want to die. (2010)
DFW-HNL-DFW - NGBC to and from Hawaii - what's not to like? (2013)
JFK-CDG-JFK - Coach, fiancé got food poisoning in Paris and was sick the whole way back - FAs were very helpful. No fun. (2015)
MAD-JFK - Lie flat J. Seat was fine for me and the husband, glad to have the tablet for sure. Good flight! (2019)

That's it I think - too bad they are gone, but would never want to fly them in Y for a west bound TATL again.
