Seat Map Vietnam Airlines Boeing 787-9 (789) 3 Class. Find the best seat on your next flight.

3A.Seat is a reasonable size with a variety of settings.
There is a useful shelf which will hold a book, phone and drink, between you and the window. Tray table pivots out and folds open, but doesn’t slide back n forth – but you can slide your chair forward so you don’t drop food in your lap, but I’m not sure it would be a particularly comfortable position to work in for too long.
Although it’s a window seat and you are facing away from the aisle a little it doesn’t seem particularly private, it would be better if the right arm rest (which feels a long way away) rose up higher to create a bit of a screen, as you’re quite aware of people walking by.
I wouldn’t opt for the front row in the middle on night flights, as there is a large screen on the wall which shows the flight map for the whole journey.
Overhead light and side light, the latter with two brightness settings. USB charger. If you prefer to use your own headphones then you’ll need the adaptor for the small three-pin socket.
There’s a small storage bin between seat and arm rest but it’s an odd shape so you can’t get much in there. Room for shoes and a small bag under footrest. There’s a cubby hole where you can find your headphones and toiletry bag, big enough for a bottle of water, phone etc.
TV screen is a decent size, with touch screen and also a separate handheld control. It folds out of the seat-back in front, you can’t tilt it up/down. Film selection, in terms of new films, isn’t particularly good (obviously includes a number of Vietnamese films).
You will be aware of people going in/out of the toilet, at the front of the cabin on the right, once the lights are dimmed, because of the light inside – so maybe a couple rows further back, or a seat on the right hand side, would be better.
Service is with a smile but I had trouble with more than one staff member understanding what I was asking for, particularly when being offered the fruit and then cheese n biscuits from a tray – resorted to pointing in the end. I had to remind them about my pre dinner drink, despite them writing it down. And there was no sign of any tea or coffee after dinner, seemingly no one was offered it. No nuts/snacks offered with the drinks; I had to go to the galley to ask.
