I'm a mid 40s NH (not pipeline or prior 121). Should be going to class Dec or Jan.
This new LOA seems to make sense to me. Those with more company time (pipeline) and more experience (prior 121) within a class should get a better number.
Although that wasn't the deal when I accepted the offer, I'm not too bent out of shape about it. I'm not that concerned about what I fly, but I'm choosing Envoy for DFW or ORD (easiest commutes from where I live).
I'm thinking the odds of getting one or the other are still pretty good even with this new seniority order (I hope so at least... gave up two other offers for Envoy).
