How does high pressure affect flying?

In low pressure air, air molecules are spread out, there isn't as much air in a given space when the pressure is low. When the air pressure is high, those air molecules become more tightly packed and the air is denser. Aircraft performance depends on this density.

If the question is regarding surface barometric air pressure, pilots prefer to fly in areas of high surface barometric pressure. This is because low surface barometric pressure is typically indicative of poor or worsening weather as well as airmass temperatures that are higher than the surrounding area.

Use the Valsalva maneuver during ascent and descent. Gently blow, as if blowing your nose, while pinching your nostrils and keeping your mouth closed. Repeat several times, especially during descent, to equalize the pressure between your ears and the airplane cabin.

Pressure is highest under the wing. That's where the air hits as the wing flys through the air.
