Looks like American Airlines is officially cracking down on AwardWallet. As of December 4, 2011, AwardWallet will no longer be able to access your AA miles balance. I just received an email saying they are testing out a new browser extension that will store your password information with your browser and will access the AA miles balance from your computer instead of their servers. There will be a beta test period, but no word yet on when the beta will be released.
Here's the email:
"American Airlines has contacted us and stated that we may not access
its website on your behalf and that we may not store any of your
American Airlines account data on our servers. As a result, in the
coming weeks we will release a browser extension which will enable you
to check your balance and still display that balance along with the rest
of your loyalty account balances; however, the data, such as your
username, password, balance and any other attributes will only be stored
in your browser so we will never have access to it. Also, this browser
extension will be accessing American Airlines website from your computer
and not from our servers. Since we do not have this extension ready
yet, please save all of your American Airlines accounts and password in a
secure place so that you can enter that data when we release the
EDIT: The browser extension has been officially released by AwardWallet and can be downloaded directly from their website. It works seamlessly for me so far, and I see it as a good workaround in case other airlines start following AA's lead.
