We appreciate your recent email to AAdvantage Customer Service.

Since AAdvantage account summaries are available in different formats
depending on how old the summary is, here's a recap of your options:

0-6 MONTHS: Summaries for the last six months are available on AA.com.
Here's how to access your AAdvantage account information:

1) Go to www.aa.com and login with your AAdvantage number and password.
2) In the 'View My Miles' section on the home page, click 'View All.'
3) Current activity will be displayed, and you can select to view
previous summaries from the drop-down box at the top of the screen.

7 - 18 MONTHS: If you require a summary older than 6 months, we offer
reprints for $50 per account, per request, regardless of the number
requested at one time.

OLDER THAN 18 MONTHS: Historic account activity information is available
for approximately the past 2-3 years and includes all mileage earning
and redemption activity (please note, travel award itinerary information
is not available). The cost is $75 and turnaround time is 5-7 business
days. To pay the $75 fee, please reply with your credit card number and
the name and expiration date on the credit card. If you prefer, you may
FAX us your credit card payment information (along with a copy of this
email) to the attention of AAdvantage Audits & Historical Records at
817-963-7820.

Thank you for participating in the AAdvantage program. We appreciate
your business.
