Southeast Asia airline fleets: Lion Air still #1. AirAsia Group to overtake Garuda, SIA in 2018

AirAsia is poised to overtake Garuda and Singapore Airlines in 2018 to become Southeast Asia's second largest airline group by fleet size, after Lion. The Lion Group has operated the largest fleet in Southeast Asia since 2014.

The AirAsia Group is planning to grow its Southeast Asia fleet by 13% in 2018, to 211 aircraft. The fleet also grew by 13% in 2017, surpassing the overall Southeast Asia fleet growth rate of 6%.

In 2018 sister airline group AirAsia X is planning to grow its fleet at an even faster 30% rate, but on a much smaller base, as it currently only operates 30 aircraft. The AirAsia X Group consists of three airlines, all based in Southeast Asia, and operates an all-A330 fleet. The AirAsia Group consists of six airlines - with the four largest in Southeast Asia - and operates an all-A320 fleet.
