Never use your frequent flyer miles from one airline and get placed on Shanghai Airlines. We had a confirmation number and ticket number from our partner, and Shanghai Airlines could not locate us in the system so we lost our reserved seats and had to go standby. Ticket counter said we'd have no issues on return flight. Guess what? We are standing in Bangkok as I type with the exact same problem with a sold out flight. Seems they don't put you in the system if you are using another airlines miles, even though they are partners, or at least that's how it looks from our end.
