Hi,
I want to order some planes, but they should be deliverd in 1 year and not soon as possible. Can I pick a delivery day???
You need to "cheat" the system. First go as if you're going to order many more planes than you want and then, at the next screen (Detailed Order Information), set the first ones to "Skip/Do not order" in the "Model" drop down box. That way you'll get later delivery slots for the ones you DO want.
So, for example, if the current delivery rate is around one per month and you need the planes 6 month later than you would otherwise get them, you need to ask for six more and then 'change your mind' on the next screen. Hope that makes sense.
But beware - this only really works if the production list is quite full. If there are empty slots earlier, you will initially be allocated the later dates but then your order will be moved forward automatically by the manufacturer
I read his question as he wants to chose an earlier delivery than announced. In that case: no, you can not get an earlier delivery.
