I agree with JadeCtrl,
some VPN services are dubious but others have a clear policy if they were to
not respect their engagements they would be liable and lose their business.
That said one can stay HTTPS all the way while using a VPN.
Any TOR exit node can be a honey-pot and there's more chances of being "data
collected"by an exit node than a VPN.
To use Tor with AirVpn you need the Windows Client :(

Disadvantages:
Poor performance
Fixed TOR circuit for each OpenVPN session
Access to .onion sites only from browsers configured to connect directly
to TOR
Dissociate TOR usage & VPN for practical reasons as mentioned above.
But don't get too over concerned by it all!
If you really want privacy throw your PC and Phone away :)
might even save your eyesight...from premature cecity.
