Bangkok Airways Reservations

One thing that bothered me about this flight. I checked seating on the flight, and it showed no empty seats to move to, but when w boarded, we found that the flight was almost empty (with many empty rows). Why wouldn't the website let me change seats when so many seats were available? I suppose we could have asked to change seats once we were on the plane, but we were already settled toward the rear of the plane and had stowed our carry-on bags.

This airline limited the carry-on to only 5 kg per person. I had to leave 2 suitcases at BKK airport with Airpotel but after boarding, I found out that many passengers were allowed to bring their carry-on exceeding 5 kilograms on board!
