Hiring will continue, IMO. How many and how often, can't really say.
If I were looking for a job today, I would not apply to Alaskan Air especially with the seniority integration that's coming up in a year or two. I think the smart thing for the company to do is to either get a new & improved contract with this pilot group or throw money at us to establish some sort of stability ASAP. With the SLI coming up and further delays to upgrade, it gives even more incentive for new hires/junior folks at both companies to leave for greener pastures given the low pay and mediocre retirement under our current contract. So yes, hiring will continue IMHO.
