I never noticed, but when overnighting to cold destinations do HP Pilots and FA's wear the long raincoats like they do on AA, and UA?

On my recent AA MR adventure, I noticed that all AA employees had the raincoats. I like that professional look.

Also, how old are the current uniforms? Do you guys think it's time for a change, and if so, to what?

I've never been a uniform-freak until recently.
