I know that every company has a few bad apples but I find this to be a little harsh. Speaking for the east group as I'm east myself I do not agree with what your saying as the majority. NO WAY. We are given VERY limited tools to do our job. Sometimes limited on something as simple as ICE or WATER. How about sometimes not even having enough pretzels or excuse me "Tidbits" to go back east from VEGAS a F'n so called HUB. So besides maybe the crew not sitting on your armrest with a short skirt and flirting with you or smiling so much it hurts what more were they to do? It is NOT the crew. My God does that p!ss me off to no end when someone gets their panties in a twist because we can't do MORE for them. PLEASE write a letter and let the company know of your displeasure. As for being treated better as NRSA I give them THE SAME service as I would a customer. I WILL AGREE that at US East you do get the occasional flight attendant that will give you the look of death if you even asked for water. We take care of each other but again you DO have the few bad apples.
I've not seen US FA's ignore pax in favor of non revs; but I see this frequently on Untied. Really. It seems part of the culture there. Odd, when you think about it.
The difference between UA and US FC has nothing to do with the crew and everything to do with what the crew is given to work with.
