If you’re buying a ticket directly from Vietnam Airlines’ website, then there’s no problem. Unlike some other carriers that charge a seat selection fee, Vietnam Airlines lets you pick your seat during the booking process (even for economy passengers). However, if you’re flying Vietnam Airlines on a ticket booked through one of their partners such as Delta or bought a ticket through an OTA such as Expedia, then you have to go through a couple of extra steps to make your seat selection.
First, get your Vietnam Airlines confirmation number. If you booked your flight through Delta, call Delta and they can provide you with their partner confirmation number. It should be six digits long. If you booked through an OTA, make sure you note Vietnam Airline’s confirmation number and not the OTA confirmation number. This will just make it easier but if you can’t get it, don’t worry.
Vietnam Airlines’ website is not bad but it’s fairly limited in what you can and cannot do. There’s no “manage my reservations” section where you can enter in a confirmation number or eTicket number to pull up your reservation, select your seat, etc. Instead, you’ll have to call them.
It took a little work to find but it turns out Vietnam Airlines does have a sales office in the United States. This struck me as odd considering they don’t have any direct flights to the United States but it makes sense considering the huge Vietnamese population in California.
Located in San Francisco, you can contact the Vietnam Airlines sales office at 1-866-677-8909. Their hours are:
