I've read through the threads here and tried to get this reticketed. Agent out of NYC said can't do. I indicated that rules say it's a straight line and EK in Bangkok is doing it. After debating it he insisted no and I have to buy a ticket from HKG to BKK. 15 minutes later he called back and said his colleague indicated it's OK. Very confusing to all. I still haven't had it reticketed, but hope now it will be honored.
