AA has been issuing e-tickets on participating Oneworld carriers for many months now (at least 6). I think only QF/BA/CX/AA are participating, know for a fact IB is now (had to get paper ticket due to one IB sector). While e-tickets are wonderful, be sure to keep your e-ticket receipt (usually ticket stock but labeled as a receipt). If your e-ticket cannot be found in the computer -- not a theoretical risk, this has happened twice to me -- that receipt is worth its weight in gold. Knowing your PNR number is not enough; finding your PNR in the res system is not enough; you won't fly without that e-ticket receipt or knowing your ticket number by heart. So my experience is that you still have a piece of paper which you must guard as if it were your ticket, it is just a 1% chance that you will need to show it at the airport instead of 100% for a normal paper ticket. When my e-ticket was not found the airline's attitude was that it was my problem and I had to prove that I really had an e-ticket in their computer; very eye-opening when it first happenend, now I am prepared and it is not a problem. BTW my e-ticket was "missing" because someone had altered the spelling of my surname, for no good reason, making the ticket "lost"; it was found only by using the ticket number which was on the receipt.
