We decided to fly down to Da Nang from Hanoi rather than get on the sleeper bus or the sleeper train that was going to take around 14h vs just over a 1 hour flight. We were told that it is most convenient and reliable to fly with Vietnam airlines, but with booking last minute and prices were over $100USD per person, it wasn’t going to be a feasible option.

This is what kept on playing in my head. And knowing how nervous my wife is about flying, I had to make a calculated decision.

The best advice though was:
If you are flying without a commitment to a time schedule, and you want a bargain, then it is ok to fly with them. If you are flying to a deadline or another flight connection, pay the extra fare and go with Vietnam airlines.
Hence, with no deadlines in place for us, we flew via Vietjet.
To my surprise, I felt like they were quite a good airline. Food wasn’t included, and it was basic perks, but you get what you pay for, and to get some extra perks only cost a few US dollars. ($2-5).
I have flow Ryan Air in Europe several times and I would have rated the service much better than Ryan Air. It may have even been on par or better than Easyjet.
In terms of value for money, it was incredible.
There was a bit of turbulence, but we arrived in Danang hassle free, apart from the 1 hour delay for our flight. But all was good in the end.
