Unfortunately you cannot change your email address manually.
Perhaps try sending an email to FlyOrDie support asking for some assistance in doing so.

Simply log in, then change your email address.

For some reason that comes with an error, try this;

I'm fully aware of that URL but if you change the email yourself you will most likely get banned for doing so as it's not optional on activated accounts, only new ones.

So if one was to change the email of an activated account by using that URL they would most likely end up with a banishment for exploiting a bug. Obviously it is a bug because if it wasn't there would be an option to change the email without the need of copying that URL from the "Click" here option of a new profile when you login without activating it.

I Strongly recommend you avoid doing this to keep your profile unless you feel someone has access to your profile and you are afraid he/she might change your password and such.

Before using that URL. take my advice and get confirmation from a Senior Staff Member to avoid a bad outcome as on here you can make the smallest of mistakes and regret it dearly..believe me I know.
