I agree no big bid will occur before age 65 is resolved. Lots of training costs to be saved by moving over 60 guys back up front.
Preaching to the choir, I know, but when a widebody CA retires you create several training cycles. One for wide CA, wide FO and narrow FO. By taking a guy off the bottom, SO, and reinputting into wide CA you save.
You know the accountants are excited about this possibility.
