This is US only, found out only at 3rd step of registration after already confirming email when they asked me to select US airport. Absolutely horrible website btw. now I am trying to close account, when I tap on profile it asks me for airport and can't do anything without filling airport and then after filling it I find out there is no automated way to close account when you check the options.
