Earlier this week, I gave Qantas' mobile check-in option a spin, and found it effectively unusable on my BlackBerry. Why that happened wasn't exactly clear, but a second attempt today to check in hasn't worked any better.
Based on the phone's error messages, several commenters speculated that the problem was due to a server problem rather than my choice of device. If that's the case, then Qantas' server is extremely unreliable, because I had exactly the same issue today trying to download a boarding pass after checking in.
After the BlackBerry failure, I thought I'd try checking in using an Android device instead to see if that would work better (yes, I'm geeky enough at the moment to travel with multiple smart phones). Unfortunately, that wasn't possible, since Qantas' system won't let you go through mobile check-in more than once, and simply advises you to use an airport kiosk or see a staff member. So I'm no wiser as to whether this is a BlackBerry-only problem, or a broader system issue.
On the original post, a Qantas staffer responded and promised an update once the cause is identified. We'll look forward to that. Other comments also suggest that Virgin Blue's system — which requires passengers to collect a small printout on boarding — isn't exactly user-friendly either, so there's clearly lots of work to be done across the board.
