“Ryanair is to shut down its entire flight booking system for a whole weekend later this month, it emerged today. Neither online or telephone customers will be able to book flights between 10pm on Friday, 22 February and 11pm on the following Monday. Flights will continue as normal during the shutdown, which has been caused by the installation of a new booking system.
Ryanair said its free web check-in service will also not be operating during the bookings system shutdown, and that any passengers affected by this will not be charged the airport check-in fee.”
