Just so I understand:

Envoy negotiated a pay raise with a sunset provision?

Seems like the smart money in a record hiring environment would be to leave as soon as possible to get on with the major of your choice asap anyway (seniority, better overall earning potential, job stability, etc)

If you’re at Envoy and sixty years old, or don’t want to leave for other non-pay related reasons, this is ok, I guess.

But it’s not going to stem the flow of pilots leaving for greener pastures the second they’re able. Maybe drum up some new entrants for a bit, but even those will leave as quickly as possible.
