About This Game

Sunnyside Regional has one check-in desk, one tired turboprop and a corgi crew chief called Biscuit. Grow it route by route until your planes fly past the Moon to Starlight Central, then take the last flight home.

Click the desk to check in the first bags yourself, then hire agents to run it. When bags pile up at the gates, upgrade the X-ray and the loaders. Buy bigger planes and book new routes. Every route you book multiplies your income straight away.

If you're not sure what to buy, click the Next hint at the top. It takes you to a good next step, or to the route worth saving for.

Renovate to fly further

When new routes slow down, renovate. The terminal is rebuilt, but every route you booked stays locked in, and booking it again pays more than a new one. Each renovation adds something to the terminal, like bunting over the windows or a fountain in the hall. Book every route at an airport and the next one opens.

Eight airports

• Sunnyside Regional is a small airfield in green hills, with a café that never closes.

• Frostpeak Alpine has cold snaps that put snow on the wings and cut your flight bonus, so de-icing pays off. The crew's snowman gets bigger every time it snows, and the passengers love him.

• At Coral Lagoon, some bags are too big for the hold, like surfboards, canoes and one very large flamingo. A seaplane flies them out at high tide, or waits for the big tide, which pays double.

• On Moon Base Alpha the bags float off the belt into a net under the roof, and then it rains luggage.

• Mars Gateway has dust storms that ground every plane. The bags wait in a silo and fly out together when the sky clears.

• Ceres Depot is where lost bags end up. You buy machines for its belt, and each one works better next to its partner.

• Saturn Ring Station has a giant Saturn in the window, and its planes come back full. You decide which handlers unload the planes and which hand bags back around the ring.

• Starlight Central is a grand terminal of brass and glass, with a desk for every airport you've built. Each desk gets more popular by the hour, even while you're away.

There are two endings, one at the Moon and one when you fly home.

A minigame at every airport

Now and then a star appears over a station. Click it to play a short round for coins and a boost. Take as long as you like, because there's no timer and you can't fail.

You'll find things in an X-ray scan, sweep a wand over a passenger wrapped up for winter, pack a plane's hold, toss bags in low gravity, squash carry-ons into the overhead bins, work out whose lost bag is whose, turn the rings of a bag carousel and set the switches on a bag sorter.

Each game ranks up as you play, and together they hide 160 curiosities. Eight regulars drop by for a round now and then, each with a little story.

Things to find

43 animal travellers pass through, including a tuxedo cat with a neck pillow and a hamster miner in a hard hat. Catch a rare bag, like the cat carrier or the drum kit, before it reaches the plane. Eleven kinds of stowaway peek out of bags, a raccoon and a red panda among them. Every airport hides five surprises, like a paper plane from the control tower or a cat in the lockers. There are 323 passport stamps, and 99 of them are Steam achievements. One is for petting Biscuit.

Away or hands on

The belt keeps running while you're away, and Biscuit has a summary ready when you're back. If you'd rather stay busy, click the desks, catch rare bags, play the jobs and time your renovations.
