Curious to see some hard numbers as well. From what I've read, by the time the intent to merge was announced last year, most of the AA list had been offered recall. The only guys who hadn't been offered recall had pretty low total length of service (1 year or less). This is my understanding but I haven't seen any real numbers.
I think if it shakes out as I suspect, the fears of many 3rd listers about getting totally shafted in the SLI are mostly unfounded. But we shall see. I think it is fair for guys who legally defer recall to not lose out because of it, or at least only lose an amount proportional to their voluntary deferral.
How does it work, in fact, on the AA contract? Let's say you are position 10,000 on the AA list, and are offered recall. You elect to bypass/defer. I'm assuming your position at 10,000 becomes frozen, and as there's movement on the list they guy who was 10,001 becomes 9,999 etc., passing you. So you do lose something.
