Install Upgrades on New Aircraft

[TheGrew]

Hi Sami
I am loving the new upgrades feature and have been fitting all my newly delivered 767-300Fs with the Blended Winglets to improve the fuel economy and range. However what I would really like is to have the upgrade packages fitted as part of ordering the new jets (obviously only where they are available) so that they arrive with the upgrades already fitted.

i agree but i have notced one odd think i had a A320-200 wanted to add sharklets and change its config from all econo to an econo+buisness classes. adding the sharklets was 14 days of maintance and the reconfig takes 3 days. so i am told that the plane will be in maintance for 17 days and yes i know 14+3=17 however there is no reason to wait tell after the sharklet instlation is done to do the reconfig of the planes interrior upgrades to unrelated systems in diffrent parts of the aircraft should be able to run concurently
