If you’re travelling with Ryanair this week, make sure you’re checked in online before they shut down for urgent upgrades.
The budget airline announced that online check-in and online bookings will be closed while they carry out work on their computer systems.
The shutdown will last for 12 hours from 5pm on Wednesday evening until 5am on Thursday.
