Apologies but just to get back on topic...
Back from New Zealand following a wedding over the weekend. Auto checkin worked like a dream, no mucking about trying to get tokens/ID discs read by scanners just a simple bar scan and bag tag printed followed by putting luggage on a conveyor (located less than 5 metres away from checking machine) and away you go.
I still don't like the lack of a human face at check in, I would have argued that was the very last thing Qantas or any other airline would outsource/ get rid of - control of the customer interface or user experience (depending on which bit of consultant speak you want). But they have and they've done it less effectively than the Kiwis.
