I haven't flown a lot, but my first plane ride was sorta unpleasant (apart from feeling the plane going up, which was fun, weeeee!)
I had a mean cold, and as a result my Eustachian tubes (the little tunnels between your middle ear and your pharynx) were clogged, not an uncommon side effect. Going down, the air pressure came back and I had a horrible sensation in my left ear, so my dad the doctor told me to pinch my nose and gently blow with a closed mouth so as to open up the ear tubes again. I did, but nothing happened. I tried again, and blew harder, and then I felt the tube opening up, followed by a piercing pain and a loud PHHHEEEEW sound. Hurt like fuck, it did. Nothing bad happened though.
