I've recently been accepted for BMI Baby and weight wasn't an issue. I'm a male weighing 15 stone, just under 6ft. They were more interested in the way you present yourself and what you can give to the airline.
If I was using governement health standards I am overweight. But in my standard I'm a fit, health man, who has bags of energy and wanting to channel this into my new career, and this was what was looked for in the interview, not wheather I was eating burgers or carrot sticks for lunch.
