If You Do Not Issue Ticket Numbers

American Express Brighton expects you to provide a 14-digit ticket number. CyberSource requires you to provide a value in the ticket number field. If you issue booking reference numbers instead of ticket numbers, you must:

■	Set airline_ticket_number to a value that looks like a valid ticket number.

■	Set airline_booking_reference to the booking reference number.

The following table describes how to create a valid ticket number.

Table 5

Steps for Creating a Valid Ticket Number

If a valid 3-digit IATA1 plate carrier code is available:	Create a value that is numeric and consists of 14 digits as follows: ■ The value cannot equal zero. ■ The first 3 digits must be a valid IATA1 plate carrier code. ■ Use a check digit for the final digit. If you do not use check digits, use a zero for the final digit. ■ If possible, validate the check digit before submitting the request.
If no valid 3-digit IATA1 plate carrier code is available:	■ Use zeros for the first 3 digits. ■ Follow the first three zeros with a 10-digit, unique, sequential number. If the unique number you generate is less than 10 digits, use leading zeros to make it 10 digits. ■ Use a check digit for the final digit. If you do not use check digits, use a zero for the final digit.
For credits:	Use the ticket number of the original ticket and not a replacement ticket.
