Rent Gates
You will need to rent gates at airports before trying to create a route to that airport. Otherwise, the desired airport will not show in the dropdown menu when trying to create a route.
Navigate to the Rent Gate area by going to Gates, and click Rent Gate. You will now see a dropdown menu with which you can select a way to view the gates for rent.
By the way, the map you see in the bottom of the screen shows all the airports that are currently in-game. Apart from showing that, it doesn't do anything. Rent the Gates
Once you have found the airport, click the Rent link to go to the next page. This page will show you a map with the location of the airport. Below that, you'll see the airport's IATA code (for example: LGA for New York LaGuardia), the amount of passengers the airport services per year, the airport's yearly cargo volumes, and the (for this article) important information: the gate costs and the amount of gates left. The larger the airport, the more you'll have to pay to rent gates. Also, if there are no gates available, you can naturally not rent any of them.
If you wish to only rent one gate, click on "OCP" (stands for One Click Purchase) and, if there are enough gates at that airport, you will immediately get one gate at that airport.
Now, choose the number of gates that you want to rent in the bottom of this page. Remember that one gate will give you ten slots, or ten possible frequencies. Click Rent to continue.
You'll be directed to a page where you're asked to confirm your selection. If the supplied information is correct, click Confirm to rent the gate(s). If something went wrong, go back to try again. Once you've confirmed your selection, you cannot cancel it. You can return gates if you don't need them.
When renting a gate, the gate cost will be deducted from your account, no matter which day it is, so keep that in mind when your bank balance is low.
Rents are always due on the first of the month. When first renting a gate, you will pay a whole month's rent, so it is preferable to start renting a gate near the beginning of a month.
