Passengers of low-cost airline easyJet faced travel chaos on Saturday as the airline’s reservation systems crashed.
Travellers had to be checked in for their flights manually as a result of the problems, which affected thousands of customers across Europe.
It took two hours for the issue to be solved, while the carrier's staff began handing out boarding passes by hand.
Press reports suggest that the cause of the problem was a network failure. EasyJet declined to comment.
