Nope, not a new hire, just realistic. Take the guppy FO vs whale capt argument. You assume that with 100% retro the whale capt gets more. Maybe. But what if the 737 FO is currently on the b scale and gets a massive bump up. Meanwhile the whale capt is lumped with lower paying wb category and receives less. Is that fair?

Better example. At l-ual the bus currently pays less than the 757. It is rumored that the aip has those two aircraft lumped at the same rate. Therefore the bus pilot stands to make significantly more than the 757 pilot from the signing bonus. Is that fair?

At the end of the day, this is a signing bonus. Every pilot on property has an equal share is this contract. I'd argue that even the fourloghs deserve an equal share as they've been damaged the most.

As I said above, take the entire amount and divide it equally among all the pilots. This is the ONLY way to avoid MEC politics as well as a completely lopsided distribution.
