Airplanes

Airplanes are the means of transport used in your airline. Their purpose is to transport passengers between cities. Each airplane has a speed multiplier and a passenger capacity. When a route is opened, an airplane is provided immediately for free when the lowest level available is chosen. An airplane cannot exceed its capacity in each flight. As the number of passengers in an Airport increases, you may need to add new airplanes or upgrade existing airplanes.

Upgrading your airplanes increases their speed and capacity, while adding new airplanes on a route allows for more trips over that route. Both of these will help you maintain Airport capacity, so as to avoid overcrowding. Airplanes can also be sold to free up funds, but you need to decide carefully, as selling the only airplane on a route will cause that route to disappear. When you retire a route for extra funds, all airplanes in that route will also disappear.

## Level 1

The first-available airplane model in the game, it's not very fast and has a very low capacity. When you open a new route, this is the airplane you will receive for free, unless you choose to get a pre-upgraded airplane for that route instead.

## Level 2

Level 2 Airplanes are notably faster and roomier than Level 1, and upgrading from Level 1 is also cheap. Level 2 airplanes can be distinguished from Level 1 by their tipped tail and visible jet engines on their wings. An event may allow you to replace all existing Level 1 airplanes with Level 2 ones for half price, or upgrade your airplane factory so that new routes use Level 2 airplanes.

## Level 3

Level 3 Airplanes are significantly faster and have more capacity than all previous levels, making them especially valuable for longer routes. They are also larger than Level 2 airplanes, as indicated by their size and the four visible jet engines on their wings. You may open a new route with this airplane for 300 in addition to the cost to open the route.

## Level 4

Level 4 Airplanes are even faster than all previous levels and have threefold the capacity of Level 3 airplanes, giving them the highest capacity to cost ratio among the Airplane levels. They are distinguished by a rounded hull shape and larger wing jet engines. These airplanes can only be acquired by upgrading from Level 3.

## Level 5

Level 5 Airplanes are a lot faster (twice as fast as Level 1) and have an even larger capacity (tenfold that of Level 1), and they are designed for long-distance, transcontinental trips. They are notably longer than Level 4 airplanes, with an acute nose tip, larger wings and a bulkier tail, but only one visible jet engine on each wing. You may open a new route with this airplane for 1500 in addition to the cost to open the route.

## Level 6

Level 6 Airplanes are the fastest airplanes that can be bought (three times as fast as Level 1), and they also have the largest passenger capacity (thirty times that of Level 1). However, they are very expensive and may only be used on very long routes. Their shape is very similar to jet fighters, with a long nose tip and wings located slightly further behind. These airplanes may only be acquired by upgrading from Level 5.

## Level 7

Level 7 Airplanes are largely similar to Level 6 ones, with equal speed multiplier, but a little larger passenger capacity. They also have a slightly longer hull, straight wings and a curved rear. These airplanes, however, are extremely rare and are thus difficult to get, as they can only be acquired from one particular event, in which case the plane will be immediately placed on a random open route. The plane can still be sold, but cannot be moved from one route to another.
