After preparing ticket from tour and travel agencies, passengers must obtain information about the overload from tour and travel agency. Overload rate is different from an airliner to another. Passengers are charged extra payment in proportion to the extra load they have. Since the extra payment is rather high, it has been arranged that the extra load of the passengers be sent via freight service which costs much less than the overload payment. This service is only provided to the passengers who have ticket and passport, and demand this service from Freight Service Unit of the airport in person.
