and no. Delta bought the A350 because all Boeing could offer was 787 delivery slots that started in 2019 and offered 77Ls since they didn't have any early slots. Price was about the same, but the A350 came faster (allowing for a faster 744 phase out) as well as a more lucrative MRO deal on the engines.
