Transport company Uber has announced a new service that could make it cheaper for people in the US to travel to and from the airport and other popular places. It's called Uber Shuttle — and it's really just a bus service offered by the company. "Whether you're a traveler, sports fan, or concertgoer, get ready because Uber Shuttle is arriving soon," said Uber's Anthony le Roux when the news was announced in the middle of May. Uber users will be able to book up to five seats on a shuttle service to big events and airports from a central place. It might be useful if you're at a big, out-of-town concert and there aren't enough regular Ubers or taxis, for example. Uber's shuttles will have between 14 and 55 seats, and people will be able to book up to a week before they travel. The company says the cost of the shuttle will be "a fraction" of the price of a regular Uber. In one example Uber gave during the announcement, the price of the shuttle was about one-third of the price of a regular Uber. The shuttle, which has previously been tested in India, will be available in some US cities this summer to help people travel to and from events. As for airports, Uber has not yet said which ones the shuttle will be available at. When it is available, users will see the shuttle as an option in their apps, and they'll be able to rate and tip shuttle drivers just like regular Uber car drivers.
