To update my own information...
E-ticketing is coming within the next few weeks.
I was in the domestic lounge at LHR on Tuesday and the place had been turned into a photo studio with uniformed staff having their picture taken in various poses around the lounge for a new E-ticketing brochure to be released shortly. It was a good giggle (and one way of passing a 1 hour ATC restriction...). Apparently the brochure will be printed and circulated shortly.
E-ticketing is already being tested on GLA-MAN bookings, with any problems supposedly ironed out before the system goes live. At the moment there are no plans for E-ticketing machines, just for paperless check-in. The new system will work for *A bookings, which will come as a relief to those who cannot at the moment select UA E-tickets because of the BD codeshare.
