Aer Lingus said its online check-in is back up and running following issues on Sunday and Monday. The airline has apologised for “any inconvenience caused” to its customers on Monday afternoon.
The statement comes after some passengers again experienced problems managing their bookings and checking in online.
“Our online check-in and Manage Trip services on our app and aerlingus.com are now back up and running following some issues yesterday and earlier today,” the airline said.
“We’re so sorry for any inconvenience caused to our customers.”
Aer Lingus was heavily criticised earlier this month, amid chaotic scenes at airports in Ireland and overseas following the almost complete collapse of the company’s computer systems.
The widespread IT failure caused 51 flights to be cancelled on 10th September, and a further four on 11th September, disrupting the travel plans of thousands of would-be passengers and leading to large queues forming at Dublin Airport.
The airline blamed a “major break in connectivity” at its UK-based network provider for downing its cloud-based IT system. The breakdown meant people could not check in online, print out boarding passes, book flights or get anything by way of effective electronic communication from the airline.
As a result, Aer Lingus had to revert to manual methods for checking people in, a move which almost immediately led to large delays and disruption.
