The ticket number is a 13-digit number that you will find on both your passenger receipt and on your boarding pass. On the passenger receipt, the ticket number is often separated by a hyphen.
On the printed boarding pass / mobile boarding pass, the terms etix, eTkt, ETICKET or ticket number are used for the ticket number. For the mobile boarding pass / boarding pass in the Apple Wallet, you can find the information about the ticket number by clicking on the info icon. The field etix contains the ticket number.
Please enter the first 3 digits in the field and the remaining 10 in the ticket number field.
