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, and Victoria's Treasurer Tim Pallas could not be happier.
Uber Air will use " Electric Vertical Take-off and Landing Vehicles" - or e-V-TOL - a new type of piloted vehicle under development that looks a bit like a helicopter and a bit like a plane.
Region General Manager for Uber Eats Australia & New Zealand, Jodie Auster, says they are better than existing vehicles.
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.
There are major safety issues still to address. The Civil Aviation Safety Authority's Peter Gibson says certification of the new aircraft is a priority.
Demonstrator flights are expected next year, with commercial flights taking off in 2023.
The location of landing pads is yet to be decided.
The service will give people more choice about how they get from A to B, and is expected to roll out to other Australian cities in time.
