And AirVPN has Routing servers used for double-hops: https://airvpn.org/status/
NordVPN for instance has a ton of servers yet doesn't label the regional locations for them in the OpenVPN filenames. They're just labeled US-1 to US-339 and I ended up having to add random configs and hope it's one near my area. Their server map isn't accurate either and doesn't show all of them.
AirVPN I'm concerned with their user logging as they have this hub area for the community that reveals your username and when you're online as well as how much data you use and have a rankings for users or servers that use the most data each day/month. There's a log in anonymously checkbox but it's still a bit worrying to me.
I also find NordVPN's labeling to be very confusing.
