In a statement today, AirAsia said it will be upgrading its Navitaire New Skies reservation system as part of its ongoing effort to improve its guest online experience.
"Flight booking will be unavailable during this period from 2.00pm (GMT +8) on Saturday, 16 February 2019 to 3.00am on Sunday, 17 February 2019 on airasia.com, AirAsia mobile app, AirAsia sales offices, counters and call centres," it said.
"Guests will also not be able to perform self-check in via the web, mobile app and airport kiosks or manage their bookings until the upgrade is completed."
The airline advised all guests flying during this period to check-in online ahead of the upgrade period and to print out their boarding passes or use the E-Boarding pass where available.
"Web and mobile check-in are available from 14 days prior to departure for all AirAsia and AirAsia X flights," it said.
"Guests are also encouraged to be at the airport at least 3 hours before their flight to avoid any travel inconvenience."
