Any ideas what happen to LNL the 6th B739ER for Malindo? it seems like that aircraft has not been flying for quite sometimes and i remember i got back from Shanghai 2 months ago and while taking the Aerotrain to the MTB, i saw LNL parked at the B2 remote stand with the engines covered over and i was wondering why that plane just parked there with the engines covered over and not been flying over the past months and that FR24 has no specific data of that plane(9M-LNL).
