Do You only get 120 when you buy all the transporting credit

So I wondering why I only have 120 when the shipping credit gives 60.

Sorry, we are not clear on what you are asking.

The Max credits is 120. 30 to start and 3 efficiency upgrades at 30 each.

Two credits are allocated to make sure that in country routes can be supported initially.

Ahh ok. I was just wondering if 120 was the max

Yes it is.
