Same account, same company

Your data lives on the OnAir servers. Switch between the Companion and the regular client anytime — same flights, same balance, nothing to migrate.

Safe to use on your real company

The Open Beta is fully supported. If something goes wrong, we step in just like for the final app. No special precautions needed.

Growing with regular updates

New features move into the Open Beta on a regular basis, installed automatically. You're always on the latest version.

FAQ

Where is the beta toggle in the classic client?
There isn't one. The Open Beta is the Companion app itself — it's a separate installer, not a feature inside the classic client. Download the Companion, install it, and you're already in the beta. Both apps run independently and connect to the same servers.
Do I need a password or an invitation?
No. The Open Beta is open to everyone. Just click Continue on the login screen.
Will my company be affected if I use the Companion?
No. Both the Companion and the existing client connect to the same servers. Your company, fleet, and finances stay exactly as they are.
Can I use the Companion and the existing client at the same time?
Yes. You can switch between them freely — there is no migration and no second account.
How do I report a problem?
Through our support platform. The Open Beta is fully supported and our team is available to help if you encounter any issue.
