I have to agree with their claim of being so cheap but afterall they really are not that cheap. As my mother-in-law flew with Nok Air from Bangkok to Phuket, her baggage was really overloaded by about 10 kg and she was charged 120 baht altogether, it should have been a lot more than that but the staff was very helpful.
When it was time to see her off in Surat with Air Asia, she was 6 kg overloaded and she was asked to pay 560 baht. Thier staff was not anywhere near helpful and din't want to compromise in any case. So yes they are low cost and low service.
