[New] Extending Terminals

Problem Description:
Despite owning and operating a constructed terminal (confirmed by viewing the particular airport details http://world4.airlin...fo.php?city=XXX), you are unable to expand your constructed terminal because the website doesn't recognize your existing one (http://world4.airlin...term.php?id=XXX). Upon entering your desired number of additional gates, the terminal construction results indicate that you must construct a new terminal to exceed your existing allotment, effectively doubling your size.

Expected Result:
By entering your desired number of gates (http://world4.airlin...p?qty=nn&id=XXX), a confirmation of construction screen should appear.

Workaround:
None Exists

How many gates do you have at the airport and how many do you want to build?

I own 20. I want to expand by 10.

Scrap that...when entering the number of gates, one must specify the total gates desired, not number of additional gates. The subsequent calculations will determine how many gates you are subject to construct. So I'm set.

Yea if you have say 5 gates and you want to build 2 more just put in 7 gates that you want to build and it will only charge you for the two extra ones
