Tandem Flying

Tandem Flying is when two players keep each-other in the air by Chirping at, and/or touching each-other.

Difficulty varies. Factors include the skill level of both players, and the amount of lag. Still, overall relatively easy.

The easiest way to do this is by both players regularly giving medium-sized chirps while flying with each-other.

Tips
It can help to focus on chirping more than flying. If you start to drift apart, either the person in front should slow down, or both players should chirp louder. It's also good to do both. You can get some practice in the Pink Desert by trying to touch the dolphins while flying, though actual players tend to move differently.
