Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“The foundation is built and incredibly stable -- the real fun starts now! We need your feedback and support to help SimAirport continue to evolve!”

Approximately how long will this game be in Early Access?

“We anticipate being in Early Access at least through summer 2019 -- and, with your support, we hope to be in Early Access even longer!

We're incredibly passionate about SimAirport, just as many of our supporters are. We hope to work on the game, hand-in-hand with the community, for as long as we possibly can.”

How is the full version planned to differ from the Early Access version?

SimAirport Roadmap on Trello

Our goal is to implement as many of your ideas as we possibly can. We hope to be working on SimAirport for a long time and, while we may not get to all of these, we'll do our best to get to as many of them as we can!

We're constantly adding more ideas to the Roadmap as we come across them, so post yours and check back often.”

What is the current state of the Early Access version?

“Fully playable, with all major functions implemented -- and they function near flawlessly.

We also finally have a set of tutorials!

SimAirport is NOT finished, however! You may eventually encounter some minor bugs. It is quite stable and performance is good; however it's not yet fully optimized for extremely large airports with many thousands of passengers (currently being worked on via the Edge branch).

There are three branches: Default (most stable), Experimental, and Edge (latest and most frequent updates).”

Will the game be priced differently during and after Early Access?

“We may raise the price as content is added. We will announce all price increases in advance on Steam and provide at least 1 month notice prior to any increase taking effect.”

How are you planning on involving the Community in your development process?

“Community involvement is crucial to ensuring that SimAirport continues to mature & evolve into the incredibly fun and engaging experience that we strive for.

Our Participation

We're extremely active participants on the community forums, and we frequent our subreddit often.

We're committed to working directly with the community to implement new concepts, refine existing ones, and to continue shipping to you as quickly as we can.

Community Involvement is Critical

This is the key to SimAirport's development process and to ensuring that we can achieve our sole goal: to create the best modern tycoon game we possibly can.

Active community participation & feedback are critical -- they allow us to iterate rapidly and evolve the gameplay at a lightning pace!

Tutorials - and TONS More!

HUGE. Seriously, this patch release is massive in both scope and volume -- it covers an extremely wide coverage area that touches on so many vastly distinct aspects. There's truly a bit of everything; lots of all-new features & objects, new systems, tons of refinements, and an absolute plethora of fixes.

Usually we'd have a bit more substantial message alongside the notes, but this one really speaks for itself so we're going to be extremely brief. Plus we'll have plenty to say over on the live stream anyways!

Dev Live Stream Tonight!
We'll be live-streaming for the next few hours tonight -- we'd love for you to join us! Ask us your burning questions, provide gameplay feedback, laugh at our airport construction skills, or just hang out and have a good time!

Live stream has ended for tonight -- we'll be back & streaming again tomorrow though and will update this post accordingly!

And now the good stuff, the meat & potatoes -- following are the full patch notes for tonight's default release. Thank you! :)

Save The Date

Happy Birthday! SimAirport turned 2 years old today and to celebrate we are doing something a little bit different this time around. Instead of an update video, this time we're going to be PLAYING it with you LIVE!

This Saturday -- March 9, 2019 -- Celebrate with us!
You're all invited to the celebration! The patch will go live on Saturday, March 9th at 10PM US Pacific. The developers themselves will then be live-streaming, taking your questions, and discussing your feedback & ideas late into the night!

We'd love for you to join the celebration -- we'll be talking about all kinds of things, and we'll be happy to answer any questions you might have about the game and what is to come in the future.

    • When?
      Saturday March 9th, 2019 at 10PM US Pacific.
      If you're across the pond from us, that's 07:00 CET (GMT+1) on Sunday morning!

    • What?
      • Developer Live Stream
        Interact directly with the devs, ask questions, learn about the game, provide feedback, and share your ideas. We'll be talking all things SimAirport!

      • Default Patch Release!
        The latest update will go live when we begin streaming on Saturday!

    • Where?
      We'll be streaming directly to the store page here on Steam and simul-casting to YouTube. We'll be playing late into the night, so stop by and join us for some fun!!

      Links to the streams will be posted with the patch notes, on the forum, and this post will be updated to include them.

See you this weekend!
We hope you will join us this weekend and we're definitely looking forward to it -- and to having a chance to sit back a bit, talk about the game that we're so passionate about, and to have some fun building an airport ourselves, too! :)

See you this weekend!

About This Game

You control everything, from the cruise-altitude decisions to the smallest ground-level details.

Challenge yourself to create an efficient & profitable international hub in Career Mode, or create an artistic masterpiece without credit rating worries in Sandbox Mode.

Construct your terminal, hire staff, sign airline contracts, tweak the daily flight schedule, configure standby gate availability, plan & design your infrastructure -- bag handling systems, roads & taxiways, fuel systems, runways, gates, hangars, service vehicles, and everything in between. Deeply simulated gameplay where each detail makes an impact -- down to the trash cans.

Simple & familiar controls for a smooth takeoff
The starter airport helps get aircraft landing & cash flowing almost immediately. Aim for profitability by scaling up, but remember: more passengers, more problems! Getting 2,000 pax out is easy. Avoiding bottlenecks for 10k+ pax will likely require different tactics!

Large & complex airports require extremely smart designs.
Moving walkways, multi-story structures, additional terminals, one-way taxiways, staggered schedules, and careful standby gate allocation -- these are but a sampling of the concepts you'll leverage on your way to truly mastering the art of large-scale airport operations.

One size does NOT fit all.
It seems simple, placing restrooms or retail areas for instance -- but it's more than meets the eye! Pax may become distracted when seating or interesting services require a long walk or are far from their gate! Carefully consider the details to truly maximize your efficiency and reap the profits.

Happy Pax, Happy Airline.
Getting flights out on-time is only part of the battle. Ensuring passengers catch their flight is another. When operations run smoothly & pax are all happily catching their flights you can be pretty sure that the airlines are probably satisfied, too! If you keep the airlines happy you can probably raise prices without creating too much fuss -- and that leads to bigger profits!

Core Gameplay
Career Mode & Sandbox Mode (unlimited funds)
16+ Aircraft, turboprop to turbine. 15 Airlines with realistic high-quality textures.
15+ research items to obtain improved transit, reporting, expansion, and other capabilities

Comprehensive Fuel System Simulation
Fuel can be a profitable saving grace or you may even decide to sell at-or-below cost as a loss-leader tactic in your effort to gain favor with airlines. Leverage the Fuel Marketplace as much as you can, too -- with enough capacity you may be able to cash in on any arbitrage opportunities that present themselves which can provide a welcome capital infusion.

Deeply Simulated Baggage Handling Systems
Conveyor to carousel, every single bag is tracked -- watch as each piece of luggage makes its journey. Losing bags is a sure way to upset an individual pax, but it also starts causing issues with the airline when occurring often. Bag handling systems can be quite complicated and you definitely don't want to become a case study like KDEN has! Take it slow and plan ahead -- building a highly efficient baggage handling operation is no easy task and requires careful planning!

Pax Info Systems
Info displays, kiosks, and public address speaker systems complete with Electronics zones to house the required amplifiers. Keep pax informed and they'll have a greater sense of urgency as their departure time nears and they're be far less likely to needlessly wander from their gate.

Robust Queues
Extremely powerful queue system provides you with full control. Supports numerous configurations include 'one-to-many' desks, to assign a single queue to multiple service stations. Optionally allows restrictions to be set per queue to allow/restrict certain types of people from using the queue (First Class, Coach, and Flight Crew) which you can leverage to create expedited queues for operational efficiency purposes.

Extremely Active Dev Team with a Proven Track Record
We have a proven track record of delivering and we've deployed hundreds of public builds since entering Early Access. Countless suggestions have been implemented, sometimes the very same day they're suggested.

We listen, we care, and we work extremely hard to promptly incorporate feedback. You'll find us on the forums nearly every single day of the week. Perhaps most important is that we deliver. This is true first class direct service -- no connections, layovers, or diversions here!

Have questions or feedback? Let us know on the forums or reach out directly via email:

We hope to see you in the friendly skies!
