Why does my ears pop really bad on an MD-80 but on any other aircraft im fine?

Question

Whats the deal with American Airlines MD-80 aircraft, my ears pop extremely bad only on that Aircraft but any other Airframe I'm fine, does it have to do with the placement of the engines?

Answer 1

perhaps that particular aircraft has a problem on pressurization at that instant when you rode it, or they go manual a develop trouble so they switch from auto to manual.

Answer 2

If anything, it may have to do with the altitude that the plane is coming from.

Answer 3

It may be the MD-80 in question's cabin altitude climbed at a higher rate than you were used to- leading to your ears popping.

Answer 4

because you have an upper respiratory infection when you flew the  md.

Answer 5

Maybe. Or you're "other aircraft" are unpressurized, such as some turboprops.
