Mate of mine got just below a BMI of 30 to join a UAE airline, 3 month medicals, he's short and wide, even the clinic agreed he wasn't over weight, but even with spending his whole life keeping super fit his BMI hovered around 33, finally because his neck was large they sent him off for a sleep study, that resulted in having to wear a mask when he slept.
His words, I don't mind what they do with me at work but in my own time having to wear this hideous mask to bed is too much.
Fortunately his bond was 3 years and not 5, he's moved on now.
Make of it what you will!!
