Easy boarding and friendly crew. There is no food offered as it is a short flight and no entertainment either…but a good experience overall.

Easy boarding and friendly crew. There is no food offered as it is a short flight and no entertainment either…but a good experience overall.

A very nice flight. It arrived on time, and the plane was very clean and the staff was very professional.

Boarding was too soon because we arrived 10’ after boarding began and they were already giving ‘final call’. We just made it. We were at gate 35 minutes before the flight. Also, the departure communication board did not list the flight at all so we didn’t know boarding had already started.

flight departure was late, with no updates on status of departure

Really good 👍 This was our first time flying with Vietnam Airlines. It was a short domestic flight, so no meal service, but boarding was organized and the flight departed and arrived on schedule. The flight attendants were professional and neatly presented. All in all, a very good first experience. We would recommend Vietnam Airlines.

We flew with their partner VESCO on a small plane, it was a really good flight. There was no food or entertainment as it’s a one hour hopper flight.

Very good flight and very kind crew Only thing is I wish there would be a vegetarian option for the meals

2 hours delay, time changes started already 2 days before the flight

The check-in process was great, and I cannot remember the name of the supervisor, but he was good and told us about the transit process very correctly and efficiently and kindly. We were given down access and the overall process was very efficient.

We boarded the plane at 1:20 pm It was hot. There was no air-conditioning It was stifling They kept us on the plane sitting there for 1 hour and 10 minutes

The most attentive crew and although we were a little late leaving ( missing passenger) flight experience more than compensated . Best flight attendants I have flown with in 50 years !!

VN661 flight, the A321 seats are starting to show heavy sign of wear and tear
