I apologize in advance to anyone who might get offended for what I am asking. My question is not intended to ridicule anyone but genuine interest to learn about the facts:
Is there a fitness requirement and/or weight limit for FAs?

While body type and weight is a personal issue and per se not the business of any employer, my recent experiences make me wonder if this holds or should hold true for FAs.

On two of my recent DL flights I had plus-sized FAs, which could not walk the isle without squeezing along the seats and pax shoulders. One actually had to walk partially sideways to make it through. Considering that FAs primary role is security and safety I was a little puzzled. Hence my question, are there physical requirements (besides the lifting overhead) for FAs and do they get re-evaluated over time?
