To put things in perspective, got a few friends that are bus drivers and they are on a base of about $38k a year plus overtime, plus super etc etc, not hard to earn between $45-60k and your home everynight.
Yup being a FA is a bit more 'glam', but you deserve to be getting a bit more for back of the clock, long haul, breathing recycled air and being away from friends and family all the time.
IMHO your selling yourself short for the lifestyle the job gives you unless your getting the best part of 50K.
