It's the other 20% that could blow out the times, who aren't "match fit". I can just imagine some relatives mucking around with their phones for ever in the checkin queue, if they didn't have someone to help the,.
I'm not a luddite - I've used mobile boarding passes multiple times on international flights which takes it to the next level (the leap of faith handing your phone over to a Thai immigration official to show the BP, for example). A great solution would be scanning into a boarding gate with RFID like you do at train gates, works almost every time without fail, unlike scanners than sometimes seem to take 4 or 5 goes to scan the screen (or ultimately where it may go for international in particular is facial recognition - like at immigration).
Ultimately there is a section of the travelling public who just aren't technologically savvy - whether 40 or 90 - even some adept at using and posting on facebook seem to struggle with some other fairly basic functionality . Maybe I'm wrong. Or maybe those folk can just fly Jetstar or Rex.
