Hong Kong Airlines review by Hoainam

booked a flight from LAX to SGN, laying over in HKG. When I boarded from LAX to HKG, the agent checked my US passport and visa and didn't say anything. I got to HKG and tried to board from HKG to SGN, the gate agent refused to let me board, claiming that I didn't have enough blank page for immigration in Vietnam. I have traveled to Vietnam more than 10 times. I stayed that night in HK, came to the US Embassy first thing in the morning, got an emergency passport, with the sticker saying it's a replacement for my old passport number. I called HK Airlines, paid them the rebooking, got a ticket for the flight to SGN, before the flight, HK Airlines refused boarding to me again, even with the new ticket and the new passport, claiming the visa doesn't match the passport number, even with the sticker. They asked me to get an emergency visa, which cost me another $250. If there was a real problem, they should have stopped me from boarding at LAX, instead of trapping and stranding me and giving me all kind of hard time in HKG
