What’s the beef with the props?
A few other people have already mentioned the noise and vibration, as well as feeling the turbulence much more due to their small size and light weight. I'll add that they're also quite cramped, especially if you're even a bit tall or broad, even if you are only in it for an hour or so.
There's a few other things that irritate me as well. You have to board them (at SYD) by either descending stairs and walking across the tarmac or getting bussed out to them, which is inconvenient, especially if you have carry on. CBR has a much better set up where you take an escalator down to the tarmac and walk along a covered walkway before turning off to your plane.
Carry on is a bit of a pest as well, given that the overheads can't fit a normal carry on. So when you walk up to the plane you have to hand the carry on over to the baggage handler and then, at your arrival airport, wait on the tarmac for the baggage handler to bring them out and you to collect it. It's generally pretty prompt but does partly thwart one of the big reasons to use carry on, not having to wait for bags. Also, if it's raining at either end this is a bit of a disaster, with both you and your luggage getting wet. I've bought
a travel backpack that has side straps to compress it flat so that it'll just manage to fit into the overhead to work around this, but every time I use it my shoulders are reminded how convenient wheeled luggage is.
Overall the jets are just a smoother experience, but they're terrible economics on a route as short as SYD-CBR, so I can't imagine we'll start seeing a lot of them.
