By Bangkok Airways Baggage Policy there are free checked allowances that depend on the type of travel class and route. In economy travels, one is allowed to bring up to 20 kg checked bags, while in Blue Ribbon, or business class, a 30 kg allowance is allowed. The size of the baggage for carry-on baggage is also restricted to 5 kg. Excess baggage fees are charged highly if the free allowance is exceeded, and this rule applies to some routes only.
