I'm with BC that the only thing you hear about is the bad cases not the good. Now my experience was a one time experience and it was great. Back 8 years ago the DW and I bought our camping buddy on the Internet from a lady in Kentucky.
We had planned on driving down to pick him up when she offered to fly him. I was hesitant but she fully guaranteed him arriving safely so I took the chance. I was fully expecting to go to the package area to pick him up when I found out that I need to go to the actual gate and I would be met my an airline employee. I got at the gate and was waiting when a flight attendant come carrying little peanut off the plane to me in his little carrier. Now keep in mind he was only 2 pounds in a small carrier but he rode up front where the flight attendants are. I was floored for sure. Obviously that isn't where the majority of the pets fly but it worked great in our situation.
