Ryanair has launched a promotion encouraging customers to sign up to its My Ryanair service.

Users signing up here by September 9, will receive a €10 travel credit redeemable against their next flight.

Customers must complete their My Ryanair profile – including name, nationality, date of birth, phone number, passport and payment details – to be eligible for the voucher.

The voucher will then “be waiting for you on the payment page when you book your next trip”, which must be booked by September 21, for travel between October 1 and December 18, 2016, and January 10-31, 2017.

The Irish carrier says that the My Ryanair service allows customers to “enjoy faster booking, special offers and a travel experience that’s tailored to you”, by storing personal details on its website.
