I pretty much always travel in uniform...
I get to keep my liquids and gells.
I don't have to take my shoes off.
I don't arrive at work only to find that I forgot to pack my uniform pants.
I don't have to carry an extra set of civvies suitable for first class and the cockpit.
My uniform doesn't get wrinkled in my suitcase.
If I want a beer on the way home, I duck in the lav and lose the bling.
