Ears popping on airplanes?

Question

If the cabin inside an airplane is pressurized why do my ears pop?

Answer 1

The cabin isn’t pressurized to sea level; that would put way too much pressure on the plane when it’s flying at 30,000 feet above sea level. Instead, the cabin is pressurized to match approximately 6,000 feet above sea level, which is comfortably breathable by people. However, there’s still a pressure difference, so you feel your ears pop.
