We booked a while back to spend a few days in Sydney, so we flew up on Monday. The Jetstar computer permitted me to check in on-line – but of course we still had to wait in line to drop our baggage (no do-it-yourself bag drop for Jetstar) and answer the “dangerous goods” question. So I don't know whether Qantas/Jetstar have got over their issues with me yet, or not. And everyone in front of us at the baggage check-in seemed to have issues of some sort. However, we had adequate time, so we couldn't complain. There was another long queue to board the plane, but I was pleased to see efforts (even if somewhat token) to enforce the carry-on baggage size limit. I guess when when an airline charges extra to check-in a bag, it serves as an incentive for everyone to try and carry as much as possible into the cabin with them.
The train into the city from the airport in Sydney was pleasant (of course, this line does have the newest trains), and we ate dinner at a casual Italian restaurant in The Rocks area. Impulsively, we jumped on the Manly ferry to occupy our evening and were rewarded with a nice view of the bridge by night but little else (in particular, Manly is very ordinary after dark)!
One lesson I've re-learned: re-activate my mobile broadband account before leaving home. Yes, we arrived in Sydney, and I found I hadn't brought with me the necessary log-in information! As good luck would have it (certainly not good management), somewhere deep in my emails was a message with just enough information to get me going.
