I was quite amused to see that the larger winglets are now referred to 'sharklets'
Yeah I love the way people go on about these sharklets as if Airbus have re-invented the wing when really all they are doing is adding blended winglets (which have been in use for about a decade) and simply gave it a new name.
Good PR stunt I guess.
I don't think the A320NEO will sell well on AWS because it is about $8-10m more expensive for a fuel burn reduction that takes a long time of the life to make savings from the original cost. People will just still go for the A320 with cheaper lease prices even if the fuel burn is somewhat more.
Also a pity IAE didn't offer a new engine in time for the project. Looks like it's between CFM Leap-X and P&W GTF.
