I don't think they think AMFA is the magic bullet. They just want a class and craft union to represent them thru these times so they can have transparency during the meetings and nego's instead of kept in the dark and bam, here ya guys go "we did the best we could do" and "they can do that brother."
I mean look at AMFA at SWA and Alaska, they too are facing the concessions ask at this very moment, and they too are staring at a possible furlough and layoffs coming thru-out this industry. The differences are, how AMFA will handle it, how transparent and informed they will be, and, it will be the members that decide on what route to take not some over paid international officers that will not get the same cuts as the membership will.
You said it best at the end, "have realistic expectations".
I am wondering if AA and United will be able to avoid the concessions ask as they have already laid off thousands upon thousands, whereas SWA has not involuntarily removed anyone as of yet, and say they will not if they can get some agreement for the concessions and in writing that they will not be furloughed thru 2021.
Here's the latest at SWA with new 7,000 Warn letters have now gone out yesterday to the rest of the groups at SWA...
