Airport

An **airport** is the origin and landing point of flights on the map. There are a total of 3,819 airports currently in the game.

## Map View

The world map shows all airports, only large and gateway airports appear in a large zoom; to view smaller airports, one must zoom in further.

### Airport Colors

Airports appear on the map in shades of blue, where the darker that blue is, the more population the airport covers. A purple airport is a Gateway Airport, which gives international flights more demand as well as making it easier to negotiate. Note that Gateway Airports can vary widely in size.

### Airport Popup

## Airport View

The Airport View can be accessed from the World Map by clicking on the airport and clicking "View Airport".

### Airport Rating

The Airport Rating section shows information about the difficulty a player would have when expanding their airline to the airport. This section details the airport rating, country rating, amount of competition, charms, and estimated difficulty.

### Your Airline Headquarters/Base

Headquarters and Bases act as hubs where flights from your airline originate and end. Each HQ/base can be upgraded up to a scale of 15. Each upgrade will increase the staff; raise the frequency cap for the number of flights along a route, and increase the upkeep cost.

The Base or Headquarters section details the established bases that the player has at an airport. If no headquarters have been placed, the player is given the option to place their headquarters at the airport. Players may place bases at additional airports.

### Loyalist Statistics

The loyalist statistics section details the amount of loyalists each airline has at the airport.

## Airport Details

### Rankings

The rankings section holds a table of Airlines that have flights to the airport. The airlines are ranked by the number of loyalists they have at the airport.

### Airport Bases

The Airport Bases section holds three tables containing information about airlines who have bases at an airport. The first table lists all the Airlines who have their headquarters at the airport. The second table lists the airlines who have bases at the airport. The last table lists all of the airlines who operate lounges at the airport.

## Lounge

Lounges attract more premium passengers to your routes.

### Requirements

To begin a lounge, you must have a certain amount of passengers, depending on the size of your airport. If the size of the airport is 4 or less, you must be the most amount of passengers transported. Otherwise use the following table:

Lounge: Passenger requirement
 5-6 (I.e. TRV, COR)
 7-8 (I.e. MNL, SYD)
 9 (I.e. LHR, JFK)

To start or upgrade your lounge, it costs $50,000,000 per level ($50,000,000 for level 1, $100,000,000 for level 2, etc.) up to level three.

### Costs

To run a lounge, there are two main costs: a per passenger and a weekly maintenance.

Per passenger, it costs $50. However, you receive a $100 payment per passenger (meaning you earn $50 per passenger)

The formula for upkeep is as follows:

```
5000 + AirportRating.rateAirport(airport).overallRating * 150

```
