Yes, as jdec141 points out, those guys in ANC have already activated (or should have, if they have not, then there is a problem, and that appears to have happened in at least one case, hence all the consternation) in their new crew position. That position would have been ANC MD11 FO. That is not the same crew position as MEM MD11 FO. So they are already trained and are simply transferring to another domicile. They aren't delaying training directly (although the company may have trained them first initially in order to fill a need in ANC, that is beside the point contractually) of anybody who is awarded the crew position in MEM.
Yes it may seem unfair that someone junior to you is making more money sooner and transferring into MEM before you can train, but it is perfectly in accordance with the contract.
If you want/need the big bucks at the earliest opportunity you need to bid ANC and be prepared to get stuck there if the merry go round stops.
Memories are very short, but just a couple of years ago hiring stopped for almost 2 years just like that. It can happen again, so if you do try to game the system and bid ANC be prepared to play it out until you can work the transfer on the next bid.
