I spoke with the ALPA attorney briefly about it. He claimed they didn’t want Delta NB to cover WB block hours. I thought this was a lazy response. In my opinion it very easily could have been included in global scope as requiring 50% of NB block hours and include language that NB hours cannot meet the WB requirement.
I assume Delta will find a way to operate at the minimum required block hours. To me partner NB flying is one way for them to get there, and the % of seats allowed Delta on those flights is unacceptable.
I also think the minimum required WB block hours is too low.

Family commitments required me to leave before the scope presentation. I hope they post an online version. I really want to like this agreement, and hopefully something in the presentation convinces me to be a yes.
