I had a print out of my Appointment, as well as a screen grab, AND a screen grab of the Email confirmation they send you. Cant be toooo careful, and cover All your bases!! LOL
First and only time I flew to BKK with KLM it took 36 Hours and included an excursion via Chengdu/ China, due to issues with the aircraft on the Manchester to Amsterdam leg.. My Bag was missing on arrival at Swampy as well, got it the following day.
