Which email address should I use to check-in my customer on a Ryanair flight?

To manage a Ryanair booking, the travel agent or client must:

1) Create an account with Ryanair.

2) Once logged in, scroll down and then you will see "More options" at the bottom. You should click on "Can't see your booking?".

3) Add the reservation number and email address. This can be either "suppliers@worldia.com" or "airtickets@worldia.com" (so depending on where the booking was made, check this first before sending the information).
