When you start the game, you have to choose a hub (airport) during the introduction tutorial. This hub will be your first base from which you will open routes.
The first hub is offered.
Choose your hub
Hubs are more or less expensive depending on their passenger traffic. Therefore, London Heathrow will be more expensive than the airport of Saint-Tropez. However, you also have to take into account the taxes you will have to pay for each flight.
To view this information, an external audit is necessary. A large airport will require higher taxes than a small airport. Besides, for a low-cost airline or subsidiary, it would be more interesting to choose a secondary airport, such as London Stansted if you want to be based in London.
On the other hand, a short-haul airline will make savings on the number of routes to purchase as it will take more time to fill them, but it will be disadvantaged regarding the taxes depending on the number of flights and not on their duration or their number of passengers.
Improve your hub
To customize and specialize your hub according to the economic policy of your airline, you can use services.
They enables you to attract more customers of one type, to change your expenses, and maybe to extract additional costs from passengers.
