Due to OW alliance, large numbers of AA EXP expect royalty treatment when to CX they are really not that important as they value their own MPC much higher internally (no offense! but are based on experiences I've read here and heard from staff).
Programs: AA 2MM, DL DM, US CP, UA PP, Hilton DM, SPG G, Hyatt Plat, FT A (addict)
As a DYKWIA who has flown only AA and BA before, I was blown away by CX F class on an award to Asia - I had avoided them due to long flight times.
I will be PPTMWY on CX in future. (PLEASE PLEASE TAKE ME WITH YOU)
Programs: BA Board Moët Laureate, BA Silver, EK Blue, Marriott Platinum, Hyatt Platinum
The worst DYKWIA behaviour I've seen was on CX, from some passengers who could have been AA EXP card holders, they were certainly from the right region, although they were actually MPC members.
It all started whilst waiting to board a mid-night flight to Sydney. Boarding was delayed slightly but a queue had formed for Business/priority already. As soon as Business was called a woman, her husband, nanny and a kid barged their way to front of the queue. After the passengers behind her objected, she screamed at the top of her voice that yes she was indeed in 'f-ing' business and she was an 'f-ing' member of the Marco Polo club. Everyone just stared at her in disbelief and a couple of us started laughing at her.
As I boarded I was unluckly enough to find myself just one row in front of the woman, the kid and the nanny. The dad wanted to sit in the same row but for whatever reason, he'd been assigned a seat at the front of the cabin. He went over to the chap in the seat that he wanted and started asking him if he would move. I suspect that the chap in question didn't really understand, or having seen the commotion at the gate decided not to help. Fair play to him. So the husband starts insulting this chap by shouting across the cabin to his wife that he was a 'f-ing' idiot for not moving. Absolutely unbelievable! At this point I decided that I didn't want to spend 9 hours near these people so I asked the FA if I could move to the mini-cabin at the rear. Peace ensued.
I couldn't get over how selfish and disruptive these people were. Absolutely disgusting, I've never seen anything like it before and I hope that I never will again. Unfortunately, the crew did little to diffuse the situation. I'd like to think that crews on Western airlines would have stepped up to have a word with this family about their disruptive behaviour, but on CX, sadly not.
