Cat 18 – Endorsements

There are no ATPCO Data Apps for CAT 18 Endorsements

Industry standards in Electronic Ticketing allow up to 147 characters of Endorsement/Restrictions to be exchanged in various formats between GDSs and Airlines.


Galileo will send up to 6 lines of endorsements, each with a maximum of 29 characters to the e-ticket vendors. However, only 3 lines with a maximum of 29 characters each can be added manually using a ticketing modifier entry. Please Note: Although Galileo send this amount of characters this does not mean they will all display on the issued e-ticket or in the order entered. All airlines have their own restrictions as to the maximum number of characters visible on an issued e-ticket.
