Hubs
OK lets break this down into rough figures to see what we can come up with.
How many passengers travel per month to the hubs?
LHR
LGW
AMS
CDG
DUS
Out of these monthly figures roughly how many will be transfering onto connecting flights to the USA as a whole??
Then lets split these figures down to daily to see what figure it comes to.
That would then give us a rough guide of the size of aircraft would be needed to operate from NCL.
