Ryanair is warning customers to check in online before 6pm today if they’re due to travel later this week.
The airline said both its website and its app will be offline from 6pm today until 5am on Wednesday morning.
It said passengers won’t be able to check in online during this time, when planned maintenance will be carried out.
“Customers who are due to fly during this 11-hour period should check in online before 18.00 on Tuesday 8 Nov,” the airline said in an update on its website.
Passengers who don’t check in on line could be charged £30 to £55 for checking in at the airport. Even if they have checked in online, they could be charged £20 if they haven’t printed off their boarding passes.
