: Malaysia Airlines will upgrade to a new passengers reservation system on June 10 and 11, causing ticket purchases and changes not available during the period.
The outage is expected from 9 pm on Saturday until Sunday and services will resume in stages from 6 am on Sunday.
In a statement on Monday, the national carrier said the normal flight schedule would not be affected during the transition.
Malaysia Airlines said however, it would be necessary for the airline to temporarily suspend certain customer-facing technology, which included ticket bookings and changes across all channels (internet, mobile, call centre, ticket counter, and travel agents.)
"MAS is working hard to ensure its customer''s travel needs are taken care of as seamlessly as possible and on-ground personnel will be on hand to offer any assistance during the nine hour of limited service.
"Passengers travelling on e-tickets need to bring a copy of their e-ticket to the airport and are advised to arrive at the airport at least three hours before departure time," it said.
The new technology will replace the current system and this refresh enables Malaysia Airlines to serve its passengers better.
Passengers are encouraged to visit MAS website, www.malaysiaairlines.com for more details before the transition period.
Meanwhile, during the cutover weekend, passengers may visit MAS Facebook (www.facebook.com/malaysiaairlines) and Twitter (www.twitter.com/MAS) pages for updated information.
