Our plane to Tawau
One of the reasons Air Asia flights are so cheap, is because they don't have assigned seating. Upon boarding, you grab any available seat on the plane. Needless to say, people line up early for the gates. I flew with Air Asia 3 times and luckily was able to get exit row for all flights. You can also pay a little more when you book online and and get express boarding (boarding ahead of everyone else).
