this is true and it’s a major issue I have the difference is Delta has a Hub to Hub/max stage length limitation on their regional network. The entire issue of the 89k vs 86k is it’s ability to be able to do a midcon in the dead of winter west bound without limitations. I routinely had to boot pax or bags doing them in an 86k jet vs what that extra 3k can give. The other factor is intro Alaska where there was a lot of bags/cargo that now won’t be limited. It’s not ok at any airline but the significance of it at Alaska is more pronounced than it is at Delta.
