I am curious about the D1 suites. The seats in this LOPA look like the regular Vantage XL (the consoles do not meet the seats in front on the applicable seat sets). E.g. looks like you can walk through each middle row. If you can walk through the middle, there is no point in having doors. Might just be a generic seat image.

For both the A350 and 777 refits, Delta had to file for an exemption to have doors on the suites with the FAA. Any word if that has taken place with the A330neo?
