The 330 fleet is split into low density (more business class seats) and high density layouts. Although scheduled to receive a high density version, I understand NCL gets a low density version about 25% of the time - don't know if this is down to demand for business class seats (which would be a good thing!) or other operational reasons.
There is a 2 class and 3 class configuration (Y/J v Y/J/F) but I was not under the impression their were to different 2 class configurations?!
Thanks ConstantFlyer!
