Thats about what the norm is for the 321neo, Delta and AA both stock them with 20F, although I will agree im not a fan of how dense they made them, especially since DL has one less row, much less E+, and gave their FAs a proper aft galley. Although the extra capacity is badly needed, especially for their EWR-FL and Hawaii flights.

According to an Airbus production tracking website, the plane has yet to do its first flight, so me personally I don't see it being delivered until at least late October at the earliest.
