NO. Flying is too easy for me, in fact I have the difficulty of keeping grounded…
So perhaps, as strange as it seems, you guys who have difficulty in flying, may in fact be more grounded in real life, which is a good thing really. And I’m envious of that.
There is some truth to the fact that I fly by the seat of my pants, literally. I think it really carries over to the dream state too.
Definitely have trouble with flying. Gaining altitude is very hard, especially when you get excited when you get high.
I’m in the other camp. Used to have a really bad fear of heights and have always been pretty awful at flying. Nowadays I’m more or less okay, but on average it’s still one of the more difficult things for me to do in dreams. The only things I can think of that are harder are any kind of “violent” expressions of dream control. Energy blasts or forcing my will on dream characters, things like that.
My problem was kind of like that. It was getting off of the ground that gave me trouble. If I was in a position where I could start off in the air (jumping off of something, for example) I could at least glide, but if I started on the ground the best I could do was a kind of semi-weightless bounding jump. When I could get off of the ground, I’d sometimes reach some kind of invisible altitude limit, where I would lose speed and start getting lower after reaching a certain height - though that wasn’t as common.
I slowly got over my fear as I got older, and got better at flying as time went on, but I can’t be sure if those two things were connected. I’d been getting creative with takeoff in dreams for a couple years - using gusts of air to push me upward (thankfully I grew up in the middle of the desert. Being shoved around by wind was a very familiar feeling), shapeshifting into a bird (changing shapes in dreams has always been effortless for me) or walking/sliding up imaginary stairs or ramps. It might have just been a matter of practice, or maybe my practice in dreams helped my fear of heights. Wasn’t really paying attention to it as it happened, so I can’t say with confidence.
Easy - no. Fun - yes.
I have problems with speed. Anything that I deem ‘fast’ has the dream dissolving and me waking up. Which means I’m a very slow flyer. It would be quicker for me to walk! 
I love walking off tall buildings (after doing a reality check!). I just float down slowly to the ground. Brilliant.
Everyone says that moving fast in a lucid dream makes it unstable. That makes me sad. Flying is relatively easy for me. I either jump high and choose to not fall down or make myself weightless. Being weightless feels easier, although easier doesn’t mean more fun. Finding new ways to do things is fun. For me lucid dreams are about new experiences. If I could just get more LDs 
Flying high and fast was a progressive aptitude for me.
At first I started gliding on floors in RD. Then I flew few cm above ground. And so on until I reached the edge of universe, and then dived back at the core of the earth searching for my wife, all these in RD.
Flying or diving easy, all the same!
Then in LD I managed to fly at will with no hesitation or uncertainty.
Blasting myself like a rocket, but much, much faster.
The absolute speed is to be there.
I almost suspect now the we all have the natural ability to fly here and in the hereafter plane, if we only choose to do so.
Perhaps, as if we live on an exile plane, LD flying might be a remembrance of our real birthright…
So I ask you if you have a similar intuitive hunch???
