Might be so, but that doesn't solve the problem they have of not filling interview slots in NA. The company has a problem with attracting, and retaining. They can give a pay cut if they want, but that will only make their problem worse.
I'm sure there will be a pay rise and some sort of improvement on the current situation. The question is wether it will be enough to fix their staffing problem. NR might be "wishing" that raising the retirement age alone would bring some back from Oasis, but I think the bigger portion of the problem is filling the bottom of the glass, not keeping the top full.
Raising the retirement age is only a stop gap, and if anything, will require a bigger raise to attract new joiners. After all, if they are having trouble attracting people when the upgrade on the Freighter is arround 2 years and the passenger is arround 10years, then it will only get worse for them when it is raised by going to age 60 (maybe 65) retirement.
