Abstract: The present specification describes a check in system for checking a passenger onto a flight. An indication of the airline and a passenger's reservation code is sent from a kiosk to a remote computer system using communications that are sent through the internet. On receipt of these details the remote computer system accesses the airline reservation system and requests a copy of the passenger name record, again using communications that are sent through the internet. The data in the passenger name record is used to check in the passenger at the kiosk. It is also used to assess whether the passenger's baggage is outside the baggage allowance for the ticket. The passenger is able to pay any fees at the kiosk further using communications that are sent through the internet. The specification also describes a baggage drop system using a similar process to issue baggage tags.
