The food quality could have been a little better. Not sure if the flight was late due to weather but that was another thing. Overall it was a good experience.

The food quality could have been a little better. Not sure if the flight was late due to weather but that was another thing. Overall it was a good experience.

It was ok. I wish if they could maintain the time.

Internal air serrulation was poor, felt suffocated after a while. Food was horrible. Seats were not comfortable at all, no leg or arm stretch room at all, even though I am not a big person at all. Dhaka transit passengers' waiting area was also horrible, dirty and unfriendly service. Middle of the journey opening previously checked in baggage was extremely unpleasant experience. I never experienced anything like this before in my 30+ years airplane journey experience.

I like food, look for extra meals or foods please

Late Biman. I will never ever go with Biman again.

There was a lot of kindness on the part of the crew. There was a strong smell throughout the plane.
