I don’t fly to often, but my in my 4th lucid dream this month, i just flap up my arms and start air swimming 
My favorite flying technique is transforming into something and flying. I find with all my transformations that deal with flight, each creature handles differently and it’s fun to test them out. Pterodactyls seem to control very well. 2-3 nights ago I transformed into the dragon from the movie, “How to Train a Dragon”. I think that’s been one I most comfortable and awesome flying experiences so far so that might be my new favorite. 
my favourite flying technique so far is just to lift from the ground, arms either pointing away from me as if i was an airplane, or held on my sides, like neo from matrix does.
furthermore, i find it much more relaxing when i can just lift up, and dont have to think about “i can fly!!1”, or need to RC before i can fly. i only managed this once yet 
Wyvern: yes, in the movie this dragon seemed very fitting in his element when he was flying
My favorite is to levitate above ground and then speed up the superman way 
I love controlling the air particles around me and making them lift me up!
OR riding a dragon! That’s always fun.
I usually use superman style in dreams
Favorite style? Hovering just above the ground. At mach speeds.
Most commonly used style? Slowly ‘willing’ myself to levitate. >_<
Swimming, feels weird but its good
I’m not doing anything physical really when I fly. I just think fly and I am, my body is relaxed arms to my side and I move forward to where I wish to go. When I’m inside I hover about 6 feet over the floor, but once outside I am flying fairly high. I love the feel of the wind, and enjoy the scenery. When I see someone below me on a road and I wish to speak to them I just end up on the road, and when leaving I sometimes jump slightly sometimes I just end up in the air without trying to get there. It is incredible to be able to fly, but I’m starting to explore other things to do when lucid.
