Looks like DL has/is nailing their connection carriers primarily... Skywest has 5% now, or 145 flights... a lot of them DL connections out west. Endeavor DL connection taking a big hit out of ATL and NYC area.
And this is just for the initial 4% decrease... so this is going to more than double by next week so I'm sure mainline will start taking serious hits starting Mon. Get ready for the epic phone wait times...
