How to schedule NEW planes that are on order

[altmants]

I notice If I lease a used aircraft, I can start scheduling the plane right away despite it takes 2 weeks for the aircraft to arrive. I recently ordered a bunch of A320s and I was wondering when It would allow me to start scheduling them? I have my first A320 arriving in 32 days(game time).
