What OS? My air can't upgrade and is out of space with like nothing installed. Curious if still macos or something else, now.

You can upgrade the disk of a MacBook Air with a larger SSD and install newer MacOS versions with https://dortania.github.io/OpenCore-Legacy-Patcher/.

Thanks a lot for that link! I know nothing of Apple stuff and a friend has got an old iMac that he thought was unupdatable but it seems there's a way. Cheers!
