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.

Pros: "the plane and the crew were great"
Cons: "There is really no vegan food on board in spite of my advance request. The transfer to T2 experience at AUH is not good and when you get there the lounge and the cafe are closed. The entertainment system has extremely limited choice/variety."
Pros: "Food was so good! Airplane was nice. Staff were friendly."
