AirAsia's online system undergoing scheduled maintenance on Tuesday, Wednesday

AirAsia, in a statement today, said during the period, online check-in or access to Manage My Booking on airasia.com or the AirAsia mobile app would be unavailable, while airport kiosks would be offline.

It said flight bookings would not be available for seven hours from 10 pm on Tuesday until 3 am on Wednesday.

However, it said all AirAsia and AirAsia X flights would operate as scheduled throughout the online systems maintenance period.

"Guests travelling during the maintenance period are advised to check-in online, purchase add-ons and print their boarding passes earlier," the airline said.

AirAsia said those who wish to check-in and drop off their baggage at the airport counter are encouraged to arrive at the airport at least four hours before their scheduled departure time due to longer queues expected.
