I don't have much to add other than say congrats on the booking. Is it the A350-900 with the ULR layout? I believe it consists of 19 rows (10-29) of 1-2-1 configuration with full layflat J. And the rest of the plane is Premium Economy (no regular economy on this flight due to length). Should be an interesting cabin to fly in, if so. Notably, Row 10 only has 1 seat in it according to Seat Guru.
