'Uber of the skies'
There are plenty of companies being dubbed the new "Uber of the skies" as apps offering the opportunity to book a plane ride proliferate, though most are not adopting the traditional car-pooling model.
Among them JetSmarter, Ubair and Rise in the US, and Victor, a European company that flies globally, allow you to book a private jet and travel in style, some even market their service at transporting pets. It's less expensive than owning your own plane, but the services are still aimed at the well-heeled.
Other companies such as Surf Air charge fixed monthly fees for Californians hoping to avoid the local ground level traffic.
If you prefer to travel by helicopter, that's available too in places. Blade offers helicopters for hire in New York and even Uber itself - the firm that runs the car app - has trialled helicopter-pooling at the Cannes film festival this year.
But America's Federal Aviation Authority has grounded Flytenow and Airpooler, US services that were operating a similar service to Skyuber's cost-sharing model, citing regulations on carrying paying passengers.
Skyuber is targeting people who may need to do a short flight, but also those who just want the experience of flying in a small plane in the seat next to the pilot.
"It is for enthusiasts and for everyone else who up until now didn't have access to this," says Mr Oliveira.
Peter Foggin, a long time pilot and director of Kairos Aviation, a UK company that sells planes, acknowledges "flight costs are always an issue, so cost sharing is a great idea". However, he notes, "the challenge is to be able to create journeys that suit the pilot and the passenger".
Others have tried before to establish similar businesses, including in the US, but none have really taken off, in part due to regulatory hurdles.
Some other online services and apps allow users to book private planes and a pilot. Those flights, even if done in private jets, are considered commercial flights and may legally transport passengers for profit. Pilots on Skyuber, however, may only share costs with people they fly with.
This means individual pilots, rather than the firm itself, are responsible for safety and insurance. Skyuber asks pilots for a copy of their license and medical certificates, and it also reviews each aircraft's legal documents. But the company states that, being just a booking platform, it's up to pilots to observe all safety and aviation rules, and to decide whether, and how, to operate each flight
