Another time standing in the -400 cockpit of UAL going from LAX-NRT (that was flight 897) I believe. As I was waiting for the captain to finish his paperwork I said hi to the IRO (bunkie) who actually appeared quite young for the -400 at UAL. He (the IRO) asked what I was flying. I said "The EMB-120", then he looked at me and said "is that even an airplane?". And no, he wasn't joking! The dude actually made it sound like I didn't deserve a ride since the Brasilia was such a small airplane.

Other experiences on UAL were pleasant. Just the 2 odd ones.
