That’s not a surprise based on cabin layout. Effectively with PS you get (roughly) double the seats per row and double the rows in the same footprint of 1 row of D1. So 4 D1 seats or 16 (again roughly) PS seats.

What is surprising to me is that they are apparently finding enough paying customers to fill all those PS seats (especially on 359s which have a LOT of PS seats). Every PS flight I’ve been on this year, the cabin was packed, with plenty of empty seats in the back. Eyeballing profiles, it appears a lot of the travelers are leisure pax (of course that’s nothing more than my anecdotal opinion).

I ascribe a lot of this to the pandemic-induced “pent-up-travel-rage”, so for now DL can get away w subpar soft product. But as soon as we start seeing slowdowns in travel spending, suddenly to a lot of leisure travelers, C+ Likely looks a lot better than shelling out for PS.
