Airholes is just another word for turbulence or instable air. It is very common & airliners normaly try to avoíd by climbing or descending or even deviating from their course. The primary reason for this is to increase the comfort level.
Turbulence/instable air at altitude is totally harmless and can be compared to bumps in the road.
Severe turbulence / wind shear or 'micro bursts' during the landing phase of flight can can however be a problem, and a couple of aircraft has crashed due to this, but it is very very rare that the outcome is that brutal.
Hope this helps

[Hi.
Can anyone explane to a newbee as me, what a airhole is ? Is there a space with no air or is it like the sea. Another steam in the air tide ?
Is it danderous for the airplanes ?
Or is it on same danger level as riding in a car on a bumping road ?]
