Are you talking about 10 tickets for 10 people traveling together all at the same time?

OR are you looking to buy 10 tickets for yourself to be used over a period of time (like 10 weeks of travel from A to B to A)?

There is information on the aa.com web site

If you are looking for the 10 trips all at different times, you might look into the Status for Sale purchase deal with the pre-paid travel card.
