My folks are about to leave tonight on the 992 flight and rang to say they got the old version 747E.
I'll wait and see what they say but when I went over in August in J we got the newer version and all was ggod.
I know Thai are notorious for swaping aircraft at the last minute but that is ridiculas.
I might try my luck this week with a visit to Thai in Eagle st and have a chat with what they can help me with.
