Airline Sketch: Route Strategy

Build your own airline on a map of real airports.

Drag from one airport to another to open a route, and a plane takes off right away. Passengers gather at every airport, each heading somewhere in the world. Carry them, and the money you earn pays for your next route.

HUB OR DIRECT?
Funnel everyone through one airport and you need fewer routes, but its runway jams and planes start holding. Direct routes skip the jam, but each one costs money. An airport with 5 routes becomes a hub with a weekly cost. How many hubs to run is the big decision.

HOW IT PLAYS
· One week is one minute at normal speed. Pause any time, or play at ×2 or ×3.
· The ring around an airport shows waiting passengers. When a ring stays full too long, the game ends. Stay in the red for too long and you go bankrupt.
· Expand airports for more route slots, runway and waiting room. Add small, medium and large jets, swap small planes for bigger ones, and drag planes from quiet routes to busy ones.
· Every four weeks, pick a reward card: new planes, an expansion pass, a route pass or a budget boost.
· Local morning and evening rush hours follow the sun from east to west. Typhoons close airports, and ash clouds force routes to fly around them.
· A game takes about 15 to 60 minutes, depending on how well you play. Save and pick it up later.

97 REAL AIRPORTS
Real airports across Korea, Japan, Greater China, Southeast Asia, Oceania, the Middle East and South Asia, Europe and North America, each at its real location. Start from Incheon; the passengers you carry from each home airport add up to unlock the next one: Tokyo Narita, Singapore, Dubai, London Heathrow and Los Angeles. Every game has three star goals.

COMPARE WITH THE REAL NETWORK
Whichever of the six home airports you start from, when the game ends you see your network side by side with the real one: which of the busiest real destinations you flew direct, and which ones you missed.

TODAY'S SKY
One challenge a day, the same for everyone, with a new rule for each day of the week: Small jets only, Typhoon season, Direct Day and more. After your first game of the day, watch an ad to play it again.

ENDLESS
A game that never ends. When an airport overflows, waiting passengers give up and leave instead of ending your game, so you can keep growing your network as long as you like. Included in No Forced Ads + Endless.

ADS AND SHOP
· Rewarded ads are always your choice: Revive, Budget boost, New cards, or another round of Today's Sky.
· No full-screen ads in your first game. After that, they appear only right before the reward cards, while the game is paused and after a short notice, plus once when a game ends.
· No Forced Ads + Endless turns off full-screen ads during and after games, and opens Endless and all home airports. Rewarded ads you choose to watch still play.
· Liveries: Paper Sketch, Sunset, Coral and Night Sky. They only change how your planes look, never how the game plays. No random items: pick the one you want.

Play offline. The network is only used for ads, usage statistics, crash reports, settings updates and purchases.

Languages: English, Korean, Japanese, Traditional Chinese, German, French, Spanish and Portuguese (Brazil).
