In flight there are 4 forces acting in pairs:

• Weight vs Lift
• Drag vs Thrust

In order to fly, lift must equal or exceed weight and thrust must equal or exceed drag.

Ease of flight scales directly proportional to air density and inversely proportional to the value of gravity.

So if you increase the air density (proportionally related to pressure) and decrease gravitational acceleration you can get most anything to fly.

At the Moon's gravitational acceleration with terrestrial atmospheric pressures, humans could fly with wings that slip over their arms.

If you're interested in a more technical treatment, I ran through the calculations in another answer and I could link that in.

Ease of flight scales in directly proportional to air density and inversely proportional to the value of gravity.

So if you increase the air density (roughly related to pressure) and decrease gravitation acceleration you can get most anything to fly.
