My Jetstar Asia record is at least 6 of 6 good flights. It's my go-to LCC. Not to mention I've done every other airline in the group - JQ, GK and BL without any incident whatsoever. But from the Jetstar Asia FB page shows, I may have just been extremely lucky.

I've only done AirAsia Thailand for two returns. One return was completely incident free. The other (when AirAsia Thailand was still based on Suvaranabhumi Airport not Don Maeng):

"Your plane has engine error. Please move to plane at gate at [E04]"
"Your replacement plane has brake error. But your original plane's engine error has been fixed. Please move back to [E02]"

I did wonder if they really solved the problem, but the plane did manage to operate normally. Any landing you can walk away from is a good landing...(and our luggage made it thru the plane swap)
