Good points all round. Yes, E-ticketing WILL be coming to BD in the near future but there is no timescale yet; the project was put back while the new (separate) res system for Baby was installed.
Incidentally (and off-topic, sorry...) I am also told the check-in for the new Baby flights at EDI will be at the exact opposite end of the check-in hall from the BD mainline flights. Not a big deal, and the two systems are separate anyway, but it doesn't exactly help the staff in terms of flexibility. They can't exactly jump from one queue to another to speed things up if they are so far apart.
