Rafael Nadal and Novak Djokovic have reunion up in the air on their way to the United States

Rafael Nadal and Novak Djokovic had an unexpected reunion up in the air on their way to the United States ahead of the upcoming Sunshine Double.

The duo have both been on the sidelines for a while, with Nadal having skipped the Australian Open and the following Middle East swing because of an injury. However, the Spaniard has now recovered, and will next be in action at the Netflix Slam in Las Vegas, after which he will make his competitive comeback at Indian Wells.

Djokovic, meanwhile, was last in action at the Australian Open, where he reached the semifinals before falling to eventual champion Jannik Sinner. The Serb then took a short break to spend some time with his family, and is now set to resume his time on the tour at Indian Wells.

With their respective arrivals in the United States syncing up, Nadal and Djokovic appear to have shared an airplane, as revealed on social media. The World No. 1 took to Instagram to share a picture with the 22-time Grand Slam champion, referring to him as "good company" along the way.

"Good company on the way to USA," Djokovic captioned the post.
