Uber is in talks to sell its air taxi business, Uber Elevate, to Joby Aviation.

While Uber is best known for its ride sharing business, the company has also been working toward deploying an air taxi service. Most recently, at CES 2020 in January, Hyundai and Uber announced a partnership to help make aerial ride sharing a reality.

It now appears that Uber wants out, as it is in talks to sell its Uber Elevate division, according to Axios. The talks are in the advanced stages, and have been confirmed by multiple Axios sources. Joby was already an Elevate partner, making it an ideal option to buy the division.

It remains to be seen how a possible sale could impact other partnerships, such as with Hyundai.
