Gate checking in existence last Monday EWR-CVG. Same as always.
I used the eService machine to print my boarding pass before going through security, although I overheard the CO agt standing at the head of the security checkpoint to say that a paper ticket or even printed eTicket itinerary is acceptable, but it must be accompanies by an ID. Incidentally, don't put that ID away - I was checked by no fewer than 4 people before boarding.
I'm flying again tonight on an eTicket and was planning to give it a try - will keep you informed.
