I am trying to purchase domestic air travel in Vietnam for a trip in April on both Vietnam Airlines and VietJet. I was able to book Hanoi to Hue online successfully (after 3 attempts) on Vietnam airlines. I have three other flights to book to complete my itinerary. I am having trouble with my credit card not being able to be verified. With every attempt I get an error message that states that my card is not verified and to check with my bank. It is a CHASE Sapphire Preferred Card. I have verified with my bank that there are no holds on my account . I have even attempted to process the transaction while on the phone with CHASE. They told me they don't see any transactions hitting the card (Other than the one successful attempt). They believe it is a problem with the website. We are experiencing this issue with both Vietnam Airlines and VietJet. We are planning to call the offices directly on Skype, but wanted to check with the forum to see if anyone else experienced this or has any suggestions.
Appreciate your help!
