They are good. If you're lucky u get to fly on their 'newer' (recently entered service with new interior but these are generally older planes by age) they have nice interior, all redone with leather seats and red carpet during heavy mx checks. pitch is not really good though.
food are on sale and are not cheap compared to places in malaysia but considering currency exchange it is still cheap.
only comment is that some of their pilots are young, new and inexperienced ( a fact that is confirmed from a source within that airline i will not disclose ). remember they had those 2 incidents in november within 2 days?
maintenance wise they are very good and a/c are pretty well maintained nothing to worry about. they have a new hangar in KLIA that IIRC can service up to 2 B737s at the same time.
however they are working on it. they are taking in cadet pilots and going through better and more intensive training. leased a B737 simulator from CAE
to be based in KLIA. Signed agreements with a local flying school academy to train their cadet pilots.
