I have a high opinion of Bangkok Airways flight experience, their jet aircraft are newer and better maintained than most in my view. However, I have flown twice on their turbo-prop planes and have not really enjoyed that experience. A bit more cramped seating but I was unaware before the flight of the non-jet aircraft and it was a bit of a shock. Outgoing from Suvarnabhumi ok but returning from Trat the landing was, I thought, close to a wing tip hitting the runway as the plane lurched hard left and tyres screeched being off centre too much. I don't think I was alone in being concerned, a disconcerting end to the flight.
