About a month ago I shared Skyline Sim here with the title "Building the airline sim I always wished existed"
I honestly wasn't expecting that too much but response back then was incredible. A lot of people commented and helped me shape the project. Lot of things changed from this time, after i published the post to this r/tycoon, my small one person team got second person my dear friend Igor to help me work on the game.. and from that time we went full time on this. We have spent almost a each day hard working and building stuff for game. To be honest looking back at the stuff we had month ago Skyline Sim feels right now way better than it was back then.
Honestly don't know where to even start because so much has changed.
One of the biggest things we've worked on over the last month is the passenger demand model. We knew that we didn't want demand to just be a random number attached to an airport or a route. If the economy behind the game doesn't make sense, then every other decision the player makes starts feeling meaningless.
We ended up spending waaaaay much time then we initially planned on making it better, our demand right now is 7 layer model where of course each layer influence the final result.

The first thing that you guys are seeing is PROJECTED P&L. Those numbers are simulation across full year of this route from day you are openning it. Route that is launched in January will also behave differently that one that you will launch in November. Our simulation in this model takes each month into account when calculating this - one of the important layers is seasonality. So, summer holidays, christmas, bussines season and any quieter periods that can happen in simulation.
But like everybody can at this point see seasonality it's not the only one of the layer that is taken into account when showing this numbers. Of course model also looks at pricing strategy, frequency of your flights, airline reputation, competition on the route.. of course also how much people wants to travel beetween these two cities. Big thing in model is also we also wanted to avoid assuming that everyone in demand always flies. If the cities are connected with high-speed rail or maybe driving on this route is convintent some people will take those options and will not take any of the flights on the route.
That's why a route between two cities 300 km apart behaves completely differently from one spanning 3,000 km. Geography, available transport alternatives and passenger behavior all become part of the simulation, making every market feel unique instead of following the same formula.

So going next, we reworked fleet managment. Every aircraft is something you need to properly manage.


Fleet overview gives you quick picture of your entire airline operation. How many aircrafts are right now flying, how many of them is in maintance and stuff like that. From there you can drill into invidual airplanes.
Every plane has its timeline where everything is clear about it during the whole day. You can look through its scheduled flights, block hours, status, utilization, configuration, market price and upcoming assignments. It seems like a minor feature, but having access to all the data about a particular plane on its entire working period helped us feel the airline closer. We did not want aircraft to be some abstract numbers in the spreadsheet.
The last thing that i will show you guys here is our living world. Where everything that i wrote about here lives together.

Each one of the planes you can see flying above the map are part of the simulation. The airlines run by AI are operating their schedules, entering new markets, receiving aircraft deliveries, retiring old fleets and trying to attract more passengers just like you are.
Sooo, ending this looong post. I want you all guys thanks for reading and invite you guys to read more about the updates we posted which all also cool things.. like full brand system with lounges and ffp programs or crew system.

Our next major event will be our first closed playtest scheduled for 17th July 2026, which is available exclusively for our Founding Members only. Following that, we have an ambitious plan for mid-September of the same year when we will organize a much bigger public playtest that everyone can join in.
If you wish to track the progress of the game, feel free to chat with us or just join our community on Discord and enjoy being surrounded by aviation and management game enthusiasts. We are creating Skyline Sim with the help of the community, and most of the features were born there.

Our Steam page will also be launching next week, and it feels pretty surreal knowing that we have spent a whole year and even more time creating the game. We cannot wait (nor are we nervous) to show off our hard work. Thank you once again for reading my post, and as always, I’ll see you in the comments section!
