Well I've now been to Bangkok and back and I have nothing positive things to say for Jet. Extremely professional service from start to finish, and all four legs were nearly free from turbulence. It was reassuring to have what sounded like an American pilot on at least one of the flights (Mumbai - Riyadh).
It also didn't hurt that I was bumped up to business class.
Anyway, if all flights went as smoothly as these I would have absolutely no fear of flying.
