I like Thailand very much and, generally, find the Thai people very charming and Thai food to be as good as it gets. I was, therefore, very disappointed to have had a very poor experience on my return from Bangkok to Heathrow this week. I appreciate that 'economy', means economy but, on my flight, the seats were very cramped and uncomfortable to the point that, if the person in front had the seat tilted back, it was impossible to use the table; the cabin crew, though efficient enough in providing service, looked as though they were bored rigid and would rather be anywhere else; the central screen on which the films were shown was of very poor quality; the announcements by the captain, the co-pilot and the cabin staff were inaudible due to very poor quality sound. The food was the worst airline food I've had in ages. I am surprised as this is not my recollection of Thai Airways on previous occasions and I should like to hear others' experiences. On my last trip to SE Asia I flew with Qatar - far and away better for food, service, comfort and in-flight entertainment.
