Airbus Commercial Aircraft, Airbus A350-1000HD

Air Liberté will be the first airline to operate Airbus' new highly efficient A350-1000 High Density layout, with higher capacity thanks to some extra emergency exits in the back section. The aircraft also includes the new, larger sharklets featured on the -900, and is the first to feature a factory-installed Gogo inflight internet antenna, more streamlined compared to the classic antenna.

Airbus had some plans for a fifth part of exits similar to the layout envisioned by Boeing for its 777-9X, unsure if that's still relevant.
