I realize this is an old thread but I hadn't seen this article before and it's interesting.
I also think ability should be the determining factor and that BMI is not always a good indicator of physical ability and health, it is just the opposite, as athletic people tend to have higher than average BMI, which is not a measurement that is that all that relative to muscular people.
But in this case, apparently, that wasn't the argument by the employee. The person was deemed obese by the standards of the employer, seemed to agree that he was obese but refused offers of help to conform to the weight standard. I'd agree with the airline's decision.
I do think some jobs require a level of physical fitness and the ability to fit into given spaces. I do think weight is a factor in some jobs (like jockeys, for instance, they are generally required to be light and small).
If a person who has a good job that they like agrees that he is overweight and requested to lose weight in order to keep the job and offered help to do so, it seems reasonable to expect them to comply.
