How to Build an Airport in MSFS 2024

• You want payware-grade detail, custom 3D modeling, or full creative control, and you enjoy learning tools: use the official MSFS SDK.
• You want your airport flyable this afternoon, shared with friends without file wrangling, and you don't want to touch an SDK: use a browser builder like Project Airports.
• You want a showpiece and have a budget: commission a scenery developer.

Microsoft Flight Simulator 2024 includes a free SDK. You enable Developer Mode inside the sim, open the Scenery Editor, and build your airport in-place: runways, taxiways, aprons, parking, lights, and any 3D model you can author or import. When you're done, the sim compiles your project into a scenery package that you drop into the Community folder.

What's great about it:total control. Custom terminal buildings, hand-placed jetways, bespoke materials, your own modeled hangar - if you can build the asset, you can ship it. Every payware airport you've bought was made this way. It costs nothing beyond the sim itself, and the official documentation at docs.flightsimulator.com is extensive.

What nobody tells you upfront:the learning curve is real. Your first session will be spent learning projects, packages, and the editor's conventions, not building. Fine details like terraforming, custom approach lighting, and navigation data each have their own rabbit holes. And when your airport is done, distribution is on you: zip it, upload it somewhere, and every person who wants it must install it - and reinstall your updates - by hand.

Project Airports is the route we build (so read this section knowing who wrote it - the SDK section above is our honest best case for the alternative). You claim a plot of real-world land on a satellite map, design the airport in a browser editor - runways, taxiways, aprons, ILS and PAPI, lighting, parking, signage, and a 25,000+ object catalog - and click build. Our servers compile it with the same MSFS SDK from route 1 and publish the finished scenery, and a free companion app syncs it into your sim, where it shows up in Free Flight search like any stock airport.

What's great about it:speed and sharing. A simple strip is flyable in well under an hour, and nobody you fly with ever handles a file - anyone running the companion app gets your airport (and every other published field) automatically, including updates. It's free to build and fly, and there's an in-game economy that pays you for flying.

Where it won't take you:you build from the shared catalog, so you can't import your own 3D models, and the most extravagant international-hub tiers are still rolling out. If your dream is a hand-modeled replica of a specific terminal building, that's SDK territory - see the honest breakdown in Project Airports vs the MSFS SDK.

Freelance scenery developers take commissions, typically priced per airport and scaling steeply with detail. It gets you payware-grade results with zero learning curve, but you're hiring a specialist: expect real money for real work, a queue, and revisions by conversation. It's the right call for a flight school or YouTube channel that wants a signature field and has the budget for it. For everyone else, one of the first two routes almost always wins.

• "My home strip isn't in the sim." Browser builder, easily - see Add a missing airport to MSFS.
• "Our group wants a home base we all fly from." Browser builder - automatic sharing is the feature that matters. See Fly a custom airport with friends.
• "I want to learn scenery development as a craft." The SDK. Genuinely. Start with the official samples and give yourself a small first project.
• "I want a portfolio piece or payware product." The SDK - custom assets are the product.

Whichever route you pick, the sim is better with more real places in it. Build the field you keep looking for.
