Flight (舞空術) is one of the most commonly used techniques in the Dragon Ball series, allowing its users to preform techniques that would normally be very impractical or downright impossible without it.
The user manipulates their ki energy so that they can levitate or fly.
It is stated in the first Dragon Ball anime series that Sky Dancing is a technique unique to the Crane School and that Master Shen is the one who created it on Earth. Flight is first seen in Dragon Ball during the first appearance of Puar, and it was named during the 22nd World Martial Arts Tournament, when Tien Shinhan and Chiaotzu are seen flying (with Master Roshi calling it "overrated"). Very soon, all the other Z Fighters (apart from Yajirobe and Master Roshi) learn the technique. Goku likely learned how to fly from Kami, during his long training at Kami's Lookout, as he was unable to do so before demonstrating his ability when he concludes his World Martial Arts Tournament match with Piccolo.
In the original Japanese dub of episode 3 of Dragon Ball Z, "Unlikely Alliance", when Goku asks if Piccolo can keep up with the Flying Nimbus, the Namekian replies that his own flying technique is significantly different and superior than the flight technique used by the Z Fighters, allowing him to fly faster than the Nimbus.
During the Great Saiyaman Saga, Gohan teaches Goten and Videl how to fly, and he further explains that anyone with sufficient power and the proper training can learn the ability. In the anime, during the 25th World Martial Arts Tournament, Mr. Satan attempts to teach himself the technique, but he fails miserably.
The way Gohan describes the secret to fly, one would assume that the flyer is putting their ki underneath them, forcing it down similar to an engine or helicopter pushing air down to rise from the ground.
Flight is a yellow Potara-item in Dragon Ball Z: Budokai Tenkaichi 3. It allows characters who cannot fly normally to be able to do so; like Kid Goku, Chi-Chi, Nam, Grandpa Gohan, Android 8, General Blue, Arale Norimaki, Master Roshi, Mr. Satan, and Yajirobe.
