Now if it's just delayed a bunch... I don't know if they would buy the Max -9. It probably has slightly higher seat miles costs than the Max 10, but that's just a guess. If Boeing keeps say, "Van - I mean Max 10 airplane - will be there in 5 minutes, it just left the factory..." would Delta wait?
So far they have stated we will have the same number of seats in the -10 as we do in the 737-900. Whether that means the 10a were going to have lie flats or just more comfort seats, the max 9 would likely just maintain current configuration.
