Travellers who have flights booked with Ryanair in November have been urged to check their departure date.
The budget airline has announced its online check-in process will be down temporarily, which could lead to holidaymakers getting slapped with an unexpected fee before they even board the plane.
The Ryanair website and app is set to undergo maintenance for an 11-hour period, with the outage starting 6pm on November 8 and ending at 5am on November 9.
