After booking a flight online today aa.com asked if I wanted to include a second email address, and it seemed to know my alternate address. I clicked "yes." Now, aa.com has only my alternate address for email. When I corrected it and hit save, it then asked me to choose and answer three "security" questions (first pet's name, etc.) and also asks for my user name. That last field has my original alphanumeric Advantage number in it but it won't let me save that, saying it's the "wrong format." IRC, I never had any user name other than my Advantage number and never had used that three security question gag. Any idea how to get around the security Qs ,and if my Advantage name is no longer useful as a user name, and how to update my email address (the one that lets me populate BPs on my phone)? Thanks.
