They would for sure fill all 100 slots ... With mostly non 75/76 pilots which will create backfill and more training. (Not our problem as pilots... Just mentioning it)

Legally the company can do this... And jsled is right, this is very similar to just merging the two fleets. Which, if they have enough pilots combine (and I think they do) they would not need a vacancy if they just outright merge them.

If a current and eligible united pilot (not on a freeze) wants to fly the 756 out of EWR I guess they should bid the next 76t vacancy and then BAT over. Clearly from the snapshot any seniority can voluntarily BAT right now? Just an observation.

Fyi - I'm junior 76t in EWR and not super excited to BAT over. But it's legal and I'm junior, so that's how it goes!
