| Change notice 7.9.2026 Update 18 All buildings now have a LOD (Level of Detail) model for viewing at a distance. Around 20 buildings were still missing one. This has further improved performance. | 25167707 | |
| Change notice 5.9.2026 Update 17 Build requirements at a glance Starting out or rebuilding an airport used to mean guessing why a building wasn't doing anything. That changes with this update. Select a building to place, and the game now shows you on the right-hand side what that building needs — a taxiway or apron next to it, a pipeline connection, a road. A checkmark tells you right away whether the spot under your cursor me… | 25139635 | |
| Patch Notes 3 Sep 2026 — Update 16 Message History Missed messages can now be read up later. Clicking the bell opens a new History tab next to the filters, listing the most recent messages — newest first, with a timestamp and warnings highlighted. You can filter by category, or show warnings only. The moment you open the history, the list holds still so nothing slips away while you are reading. New messages keep collecting in th… | 25107927 | |
| Patch Notes 2 Sep 2026 — Update 15 Road Tunnels Roads can now run underground. You'll find the Tunnel portal in the build menu under Ground , right below Street. Place one portal at each end — press R to turn the entrance — then connect them underground with the road tunnel. The road tile in front of the entrance is added automatically. In the Underground view, a green frame shows you when two portals are truly connected. A tunn… | 25085588 | |
| Change note 29/08/2026 – Update 14 Switching a runway during operations Fixed: When a runway was switched to "arrivals only" during operations, aircraft already assigned to it for departure would stop. They waited indefinitely for a clearance that could no longer be granted there — whether they were still taxiing towards the runway or already holding at the threshold. Affected aircraft now look for another departure runway right… | 25010976 | |
| Change note 28/08/2026 – Update 13 Ground handling at large stands Fixed: At large cargo and passenger stands, ground handling could fail entirely. Aircraft waited indefinitely for refuelling, loading and customs even though the progress bar looked complete — but no vehicle was ever dispatched. The cause was the search for the service area next to the stand: it only checked two of the four sides. If the service area lay to the r… | 25000463 | |
| Change note 27/08/2026 – Update 12 Change note 27/08/2026 – Update 12 Cargo buildings The buildings for cold, live, express and hazmat cargo now hold a maximum of five vehicles. To operate more vehicles, build additional facilities. The fleet research remains unchanged — at the highest level, 25 vehicles per cargo type are still possible, spread across several buildings. The vehicle window now shows each building's occupancy alo… | 24974098 | |
| Change note 24/08/2026 – Update 11 Signs can now be rotated. | — | |
| Change note 24/08/2026 – Update 10 Decoration Trees and signs can now be demolished and moved with a single click. | — | |
| Change note 21/08/2026 – Update 9 Passenger boarding bridges The passenger boarding bridges have been adapted to the redesigned terminal buildings and now dock directly at the terminal again. | — | |
| Patch Notes – August 20, 2026 – Update 8 New: The large tower can now be upgraded further: the new research "Large Tower +" raises its capacity from 50 to 60 aircraft. | — | |
| Patch Notes – August 20, 2026 – Update 7 All four terminals have been reworked with sharper textures and better proportions. The terminal extension has been adjusted to match. The new models appear immediately, including on terminals you have already built. | — | |
| Patch Notes – August 18, 2026 – Update 6 New: Longer runways — 12 tiles for small, 21 for medium and 31 for large (about 30% more). Runways you have already built stay exactly as they are. The new length applies to every runway you build from now on, and to new games. | — | |
| Patch Notes – August 18, 2026 – Update 5 Fixed: Aircraft now always taxi to the start of the runway, no matter which side they enter from. Previously they took off from the middle of the runway depending on their approach. | — | |
| Patch Notes – August 16, 2026 – Update 4 ew: The options now include an "Audio" section with separate sliders for music and sound effects. | — | |
| Patch Notes – August 15, 2026 – Update 3 Fixed: After starting a new game from within a running game, newly built buildings were sometimes not recognized. | — | |
| Patch Notes – August 14, 2026 – Update 2 Fixed: The Customs Office and the Weather Station were displayed too small after being moved. Changed: During a Night Flight Ban, aircraft now remain at their parking position instead of taxiing to the runway. | — | |
| Patch Notes – August 14, 2026 – Update 1 Fixed: runways were displayed incorrectly after loading a save. | — |
