Let's keep in mind that this is an internet board filled with extreme, bitter, and angry opinions... not everyone feels the way some express here. Thankfully, MOST of us that do disagree are able to discuss things maturely...
I know plenty of UAL F/As who are happy with the AFA and respect the constitution and by-laws they and thier predeccessors worked so hard for. That said, while the general feeling at US has always been DOH in any merger or acquisition, I'm sure there are some who feel different. To each his own.
I was on an Airbus trip shortly after the Shuttle had fully integrated in to mainline. The other two flight attendants had been in the same class.... at Eastern Air Lines. One had gone to the Shuttle with Donald Trump and kept EAL seniority. The other had stayed with EAL until the end, and then started over at USAir. When Trump sold the Shuttle to USAir, the F/As kept thier seniority. When Shuttle Inc fully merged into US Airways, they kept that same seniority that went all the way back to Eastern. If I'm not mistaken, the number one US F/A became number two.
So here was two flight attendants who began thier careers together but had significantly different seniority (a few years) at the same company years later. Was the F/A from USAir bitter towards her former classmate? No, they had a great time catching up... Neither of them ever thought they would be at US Airways, one chose US after EA, one ended up there more senior simply by being bought and sold numerous times. They even joked about who they might run into at United (this was during the merger time). It just goes to show that we can't predict where we end up. I'm sure those pretty, California-girl PSA stewardesses never thought they would be flying transatlantic flights for an east coast carrier with little western presence, just as those Pan Am stews never thought they'd see a 737 to Omaha. Our uniforms, aircrafts, and identities change, but we don't. The only thing we have to hang onto is our seniority.
Another thing worth hanging onto is brotherhood and respect for our peers, no matter where thier paycheck comes from. Let's hope our wonderful industry and it's wonderful people bounce back, and hope for less heartbreak and ruin rather than for more.
