My wife and I fly to Mexico from Canada each year for Vacation (6 hrs) . I love flying and never had a problem with it, but my wife is somewhat uncomfortable, and takes a couple of Gravol tablets an hour before take off. It's also used for motion sickness. She snoozes off and on until we get to Mexico. As for your ears popping, this is normal. High altitude flights, the cabin is pressurized as the plane gains altitude, but you may still have popping in your ears. Low altitude flights that are not pressurized, the air is thinner, and more pressure is put on your ear drums. If you have ever gone scuba diving or snorkeling, you will have to equalize the pressure on your ears by holding your nose, close your mouth and blow against your nose sinus. This will cause your ear drums to equalize the pressure. This works for flying also.
