I see on a flight tomorrow that the main economy cabin is packed solid but there are a lot of comfort plus seats, most of them. I suspect that on this flight, maybe most people are booking basic economy or non-Comfort Plus economy so Delta is stuffing the people in the back to punish them instead of spreading them out.
Someday there might be movable seats so the leg room of basic economy is reduced?
I don't see them further chopping up Main cabin section just for BE fares. Presumably, you are talking about 9:59PM flight tomorrow since every other flight is W0 or W1. Note that Silver Medallion/Amex Reserve 24 hour upgrade window for this flight has not opened up yet.
