A word of caution about VPNs
Last Wednesday I was booking flights through my work computer while using the company required VPN for security. Everything went well during booking. Later that night though I received an email from AA saying that my account was locked due to suspicious activity. I called for help but their security office wasn't open.
After I finally was able to contact them, they said that my account was accessed from another country so they locked it. If I wanted to reset it I would need to get another AAdvantage number and register a different email. If I chose to stay with my current AAdvantage number and email, AA wouldn't support me in case of points theft.
I asked why AA doesn't just text me or email me like Google does when something weird happens before going nuclear and they just said they didn't know but that's how it is.
So a word of caution, don't use a VPN routed through another country while booking flights.
