Last year I was through Juanda in Surabaya on a couple of Garuda flights. I was taken aback by the Air Asia advertising posters in the terminal which had a strap line "Air Asia - the airline with balls". I am led to believe that was an oblique reference to the football club QPR, in which the Air Asia CEO has an interest, but I was immediately put off by it and thankful I was on Garuda.
There has been chat on here about the culture of Asian airlines in general, but that strap line sounds a bit iffy to me and perhaps "just" an indication of attitude in management?
I have been a passanger on Air Asia flights roughly monthly for the most of 2014 due to frequent trips between Jakarta and Kuala Lumpur. There is a lot to dislike about them (if you want to drink water you have to pay). But they do have a better safety record than most other carriers in the region (iirc this is their first major disaster).
No major complaints as a passenger, other than the recommendation to pre-book meals.
