1 wonder in which area AK con cooperate with Malindo.. "okay Rusdi here's the deal. Say i order another 100 aircraft but this time from Boeing, u can order the same but from Airbus.. Then we can share the intel about the pricing, we can negotiate for more than half!"
Pilot training (pilots of both airlines trained by CAE), cabin and ground crew training, catering, maintenance, procurement, alignment of flight schedules, etc etc etc. Both airlines have huge operations in their respective home country so collaborations can be potentially very beneficial.
