Credit Card: We can accept payment by credit in advance by online payment link or at the time of delivery by imprint method. For your protection, in either case, we will need you to verify with a legal identification (e.g. passport, drivers license) before charging your credit card and your signature on the receipt of the credit card payment at the time of delivery. We will inform you in advance of purchase of any credit card fees that may apply. For international tickets departing from Vietnam, we only accept the imprint method payment proceeded in our office in Hanoi or HCMC.
