Just booked 2 tickets for me and the wife...Still haven't told her yet, not sure she'll be as excited as me to do this trip
673 USD for the both of us.
HAN-DOH 11 March (2 hour layover, wonder if its the same plane going back?)
DOH-BKK 12 March (nearly 2 days in BKK, I love the shopping there)
BKK-DOH 14 March (14 hours, so will have a look around)
DOH-HAN 15 March
Found by searching first on kayak.com, there were about 6 options for these dates. There were even 2 options for the HKT-DOH-KUL route available too.
Think i'll wait a while before working out how to get to Hanoi to see what happens with others booked on this adventure!
