Right Back Into the Air is an achievement in Run 3.
This is actually quite easy as the Student as well, due to her special ability, she can choose when to land, making her land on the ramps accurately.
The Angel makes this achievement ridiculously easy. If you dash right before hitting a ramp, you will go flying in the air. This boost will let you get to the next ramp. Even more beneficial, the dash is recharged as soon as you hit the ramp, so the entire thing is a chain.
If you get lucky with the Gentleman, you can just hold up and fly through the level with your electromagnet.
