The WiFi & sat comm hump is fitted at Boeing, I did read about a new WiFi contract that will significantly increase band with.
All Norwegian aircraft have CPDLC but require VHF contact for it to work, sat comm will be installed shortly, the big benefit will come East bound when due to average TWC the fuel required and thus the aircraft mass is much less making a higher cruise level possible further reducing fuel required.
West bound head winds means that in most cases it’s not possible to get above 340 even if we could prior to NAT entry, as soon as we leave NAT off the coast of Canada we climb up to 380 this saves around 2% on the remaining couple or so hours.
