Does the 50k a year include the allowances, that most F/A seem to horde to pay off morgages, and thanks to the bunch of them who made the ATO start to tax allowances.
I am not saying you do a bad job, however you are on a world scale at or near the top of the tree in dollar terms for the position. They are trying to stop the QF pilots and others earning more who are on a world scale near the lower end of the scale for their positions so you don't think they are going to try and get you?
I can think of few people who have ever been in face to face service industries that stay in the same job for 20+ years, so being a F/A must have some attraction, most don't seem to go out much in slip ports maybe it is something else, perhaps it's a fair stack of cash.
