Malaysia Airlines began taking delivery of six Airbus A350-900 aircraft which is leased from Air Lease Corporation in 2017 to replace the ageing Boeing 777-200ER fleet and was the first A350-900 operator to offer First Class. They are configured to accommodate 4 seats in First Class, 35 seats in Business Class and 247 seats in Economy Class (286 seats in total) after MAB CEO, Peter Bellew said premium economy seats "would erode our business product and revenues". On 12 December 2018, First Class was rebranded as Business Suite Class.
