How to maximize ordering used planes?

[Lambert_M]

Hi peeps!

I am just wondering what the rules are exactly on ordering used planes. Obviously, I can only order 2 planes in a single day. But after that?

I have to wait at least 1 day to order 1 other plane?
I have to wait 1 week from the first order to order 2 more planes?

This is my conclusion from reading the forum posts, but would like someone to confirm that my understanding is correct.

In which case, it would take me 2 weeks and 1 day to order 7 planes?

You got that right. So, to the following would maximize the UM:

10th: 2 planes
11th: 1 plane
18th: 2 planes
19th: 1 plane

and so forth.
