Hello Zoirrutaigh28
Why do you need the ticket number? This is something the ticket inspector would need, if at all.
It is correct that tickets are sent as PDF; one PDF for each ticket.
The ticket number is in the upper right corner, above the passenger’s name.
We discourage you from mentioning order numbers or other ticket details in a publicly accessible forum as ours. Such data, including your personal data, could be abused.
Kind regards,
Roland
