I have been using the E-Ticket exclusively since its introduction.
My first trip on the E-Ticket was on USAirways' Metrojet to IND. I had decided to try this new technology. We were going from PVD to IND. Since both me and my mother had only carry-ons, we went directly to our gates.
I was worried that something may go wrong, so I came prepared with print-outs, phone numbers and the likes. However, once we showed our IDs we received our tickets, we found there was nothing to fear.
I have had no problems with this format. I think it's better than the ordinary paper tickets because it's flexable (from the airline's POV).
Oh-- I do have a good story about this though! This past Thanksgiving, I took United Airlines from Lafayette/Purdue University Airport to O'Hare, then a connection to Providence.
Since I had a long layover in ORD, I decided to get some pictures of planes. So I cruised the terminal snapping pictures. Then as I began my journey back to my gate, I found I had lost my ticket! Oh no! Time to panic!
I went up to the United Customer Service desk, expecting to get upbraided and told "sorry, sucks to be you!" However, what I found was a nice lady who told me, "don't worry... you have the E-Ticket. No one else can use it." She reprinted me a new one and I was off to my flight!
I say go with it! However, do bring a copy of your intinary with you... just in case something does happen.
