When TWA was bought by AA, there was an offset of about 10 years. 40% or so were stapled to the bottom.
Then 9/11 happened and most of those stapled were promptly furloughed. Retirement went from age 60 to age 65. Most of the furloughed were out for better part of a decade.
The TWA FA had it more extreme. They were totally stapled. Meaning the #1 35 year TWA FA was stapled below the 7 MONTH newest AA FA.
What is done is done. Most everyone licked their wounds and has moved on. It is what it is.
But I share this so when the SLI comes out, no matter who thinks they ‘lost’ or were ‘cheated’, there are pilots (and FA) in this industry who had it worse. You will be treated much better, so grouse, complain, argue; but eventually get over it and move on.
