Actually, no. The Letter 3 awards of APA seniority numbers to Eagle pilots took place sometime around 97 or 98, as Letter 3 was the ugly product of a 'Four Party' agreement by which the APA allowed specific scope relief to AA/Eagle Airlines to even operate *jet* equipment of any size with pilots not on the APA list. The flow-through was Eagle ALPA's demand for allowing a 'Flow back' clause where APA pilots would wind up at Eagle with 'super seniority' and Captain seats if AA furloughed because Eagle got jets. AA/Eagle management then pulled a fast one- the scope relief limited the number of jets with greater than 44 seats. That's why we have Embraer 140s- they're just lengthened Embraer 135s with 44 seats. This, of course, made the APA hopping mad.
The TWA acquisition happened in January of 2001, several years later. I'm not 100% on my timeline, but by the time list integration was being dealt with, 9/11 had happened. Now, you have many many TWA pilots that were sold out by their ALPA leaders in the integration that were furloughed. Many wound up on the street, with seniority status later determined by arbitration to be equivalent to that of an undated new hire. Then, you had TWA pilots that got APA numbers, but flowed back to Eagle- as 'super senior Captains'. (Contrary to legend, many of them were beyond super cool, and not the super dicks some made them out to be.) And then you had Eagle pilots, who as of 1998 had been given APA seniority numbers with the promise that they'd get called up to the big leagues 'any day now'. This effectively made many Eagle pilots senior to the 'furloughed, no-date, no number but with recall rights TWA pilots', entirely by virtue of the Letter 3 nonsense happening three or four years prior.
Meanwhile, 15 years went by, the last of the flowbacks took recall within the past few years, the Eagle pilots with numbers finally got made whole, and the first of the previously harmed Eagle pilots (the 824) will start filling new hire classes in the next few months. Not even the whole classes- Eagle still has to plan to backfill the attrition. Guess what- MORE ARBITRATION!!!!!111! Yay.
Now, enter the merger. It's enough to make a guy's hair fall out. Even still- At this point, the 'numbered guys' are all gone. AA and USAir will merge lists, and you guys can feel the pain of what we call 'Four Party Talks' where four separate parties sit down to negotiate- that hate each other. And then we throw in the East vs. West drama, and we have SIX PARTY TALKS!
My brain just 'sploded. But hey, at least I might see the left seat of an RJ sometime.. after 6 1/2 years. Yay.
