Even if we had a hatless leather jacket option, I'd probably still wear the standard-issue uniform.
Personally, it harkens back to the Pan Am days where you not only displayed authority, but also you represented your home country.
Narcissistic, absolutely, but you'll walk around CDG and you see sharply dressed KLM and Air France crews, all of the pilots in uniform coats, hats, and the flight attendants looking absolutely sharp, good postures, representing their airline's brand.
Now you see some US carriers, there's a guy in an unzipped leather coat, huge gut, another one with an unbuttoned blazer with his hat in his hand, and another one walking around in a civilian coat followed by a mis-mash of flight attendants in cat-hair sweaters, elastic waistband pant suits and shuffling around like they're slew-footed overweight zombies.
Maybe I'm old school but appearance does make a difference in representing your employer's brand and also when you've got to handle an issue.
My employer takes this seriously, I
voluntarily signed up to work there, I'm not about to bitch about their expected appearance standard.
I want to serve Corn Dogs at the mall, but OMG I HATE THE HOT DOG ONNA STICK UNA-FIRRRRRM!
