8 segments in 2022, It's literally a 50/50 shot if both are open to line up in but these lanes don't mean anything when you have people boarding in Main 2 or 3 hoarding over them blocking people from boarding properly. Nothing Delta can do really to fix that. I remember one flight last year the gate agent was being super involved forming lines for D1/Diamond then Priority/C+ etc.
I can count the times where I wait for FC or C+ to be called and by the time I get out of my chair and over and work my way through the crowd she's calling the next group because no one can get through the main cabin hovering over the entrances.
