The problem here is Matercraft made a move from AAI to LUV, with the intent of moving up, and now finds himself staring at scenarios where he might end up junior to people he was formerly senior to. I've heard of a few similar cases in other mergers, including ours, and this kind of thing simply makes you sort of shake your head. In a way, you gotta feel for the guy, not because what's happening is unfair, but because it's bad luck.
Then again, the moves mastercraft made, and the choices he took, are not the responsibility of other pilots. Some may have made the reverse calculation and made a conscious decision to stay in anticipation of a merger, while others simply remained at AAI because it was good enough for them. Regardless of how people ended up on the two respective seniority lists, the SLI should look at the pilots groups in general, including specific demographics, to craft a fair outcome. That doesn't entail correcting an individual's fate, or altering their place within a respective list. Mastercraft is a junior LUV pilot, and that's how he'll be considered in the SLI.
