When you think of "affordable travel" buses, taxis and trains are likely to come first to mind.
But within a few years air travel could be up there too - if you're in Melbourne.
Uber's picked the city as a trial site for its ambitious aerial ridesharing service Uber Air.
It joins Dallas and Los Angeles as a test centre.
Uber Air will use " Electric Vertical Take-off and Landing Vehicles" - or eVTOL - a new type of piloted vehicle under development that looks a bit like a helicopter and a bit like a plane.
Passengers will book rides via an app.
And board their flights at "Skyports" - landing pads located on the top of buildings and car parks.
A 19-kilometre trip to Melbourne Airport that may take almost an hour in peak traffic, could be reduced to nine minutes by air and cost around 70 dollars.
