Oh man, Platinums are about to lose their minds when they have trouble finding overhead bin space in C+...
It's somewhat disappointing as nothing they are changing will really speed up the boarding process. I really wish they would mix in some lucky back of the bus folks in with the First/SKY boarding if only to make boarding faster. I know, when pigs fly and all...
edit: I realize now that if you are upgraded to C+ then you can still board with the new SKY group. Oh my god. Why would Delta do this? This will literally slow the boarding process down even more! What harm does having Plat/Gold board with SKY if they are not in C+? Delta is literally trying to slow down boarding even more.. I don't understand.
