Question on Dimensional Dervish

I'm currently playing in a long-running PF game, and was thinking of making a backup character for when things go awry. I was looking over monk, and they look fun. Then I found Tengu, which looks really fun.

Then I found Dimensional Dervish, and that just looks too fun to pass up.

My question for the playground is this: When using Dimensional Dervish, if I have enough move speed, can I use my attack actions against a flying target before settling back down on the ground? Or do I need to stay grounded to use my attacks?
