A tip that most of you probably know, but if you want a receipt for any kind of AA ticket (TA issued, Award, AA.com, Expedia etc.) I've always been successful asking a check-in / ticket counter / AAdmirals Club agent to print one for me, on ticket (boarding pass) stock. It shows the name, fare calculation & fare paid, and since it's an actual agent printing it you get all the previous tickets if it went through reissues (Miles + Copay, SWU, etc.) Sometimes messing around on the website isn't just worth it if an agent can do it in seconds.
