i don't think they earn more than 5k per month for working experience below 5 years, I have a friend that works as MAS air stewardess too, flying domestic and international. She even asked me to introduce her any part-time job to help with her monthly expenses.

The pay is by per flight, there will be the allowance to claims but somehow u also need to spend it on your meal and outing etc, if your flight canceled, you won't get any allowance for that day.
