A ticket is issued by a carrier or its authorized agent, and with its issuance it is assumed, in accordance with JAL's Condition of Carriage (International Passengers and Baggage), that an international condition of carriage has been agreed to by the airline and the customer. Ticket information is stored electronically, and the customer can confirm it with the e-ticket itinerary/receipt.
Always abide by the order of the itinerary noted on the ticket. If the customer does not follow the itinerary in order or has a segment that will not be flown listed on the ticket, this could invalidate the ticket, including all remaining segments, and render the ticket unusable in accordance with fare regulations.
Only the passenger whose name is on a ticket may use that ticket. Names cannot be changed and tickets cannot be transferred to others.
You need to present the e-ticket itinerary/receipt at check-in or may be asked to present it during immigration procedures, so be sure to have it with you.
