Clearly the answer to my question is one cannot. I don't want to print it - I don't keep things in hard copy (unless I have to). Not even to pdf and then email it to myself. One of the ways I organize my itineraries in my email client (nice to have it available when offline). They're all there. Even having this one as a pdf attachment wouldn't be as accessible I would like it. Copy/paste from aa.com doens't work too well.
I guess I will just have to call EXP desk and ask them to re-email. I would have thought this was not complex functionality to have on aa.com
