Is it just me, or is that front lavatory between door 1L and the mint cabin ridiculously large for a narrowbody? Seems like that would be a nice 'amenity' as well if it is.

Also, given 190 seats in a neo in B6's typical all-coach config, I'd expect to see 100ish seats in the rear, depending on how much goes to EMS and potentially additional galley space.
