Question marked as
An early 2015 MacBook Air can be upgraded to the latest version of Monterey macOS 12 but no later.
See instructions in: How to download and install macOS - Apple Support
Be aware that if you upgrade to Catalina 10.15 or later you will also need to update any non-Apple 32-bit apps. See: https://www.stclairsoft.com/Go64/
