Well, I can provide a first hand account of Air Asia operations.
I very recently, did 6 sectors with them within Asia. My observations:
Cabin Crew ... mostly spot on. More observant and more thorough than a lot of QF flights I've been on.
Piloting ... just observations, without comment ...
- on no sector was reverse thrust ( that I could see or detect) used on landing ....
- based on engine noise and experience elsewhere, reduced thrust used on all takeoffs
- One "hard landing" ... for which the Captain apologised
