An interesting consequence, be it unintended or not, will be frustrations for PMs and DMs who may well see open C+ seats on a seatmap but won't be able to select them via their complimentary C+ access benefit because C+ will actually be sold out with those empty seats being held for assignment at check-in or at the gate for those who bought C+ Basic. I wonder if DL will account for this and just grey out C+ seats if C+ becomes sold out so as not to create a false impression of available seats.
