Entertainment options are slightly lacking (in terms of variety and number of movies and tv shows) when compared to other airlines.

Maybe a few more offers of drinks and snacks during the flight.

Over all I was happy with my flight the only thing I was not happy with was the fact Vietnam airlines changed the times of the second leg of my trip which meant I had a layover of over five hours instead of just over two which I originally booked plus they have changed the times of the first leg of my return trip

would be nice to be able to check in and book seats a bit earlier than 24hrs before departure especially seats

Seats were quite small and not so comfortable and although the airport was very quiet at 4am when we landed the bags were very slow to come onto the carousel. I think just one person was offloading them as some came off immediately but it took 45 for ours to be offloaded. Overall though not a bad flight. Good entertainment package and mid meal food and bottled water was available if you wanted it
