about 4 weeks ago I had a guy (about 19 years old) jumpseat on my plane without my knowledge. When I found out and asked why he didnt come up front to say hi/ask for a ride upon reaching out destination, he told me "My flight school told me I get umlimited jumpseats when I passed the program and became an airline pilot." I tried to correct him but he cocked an attitude. Ive had this on more than one occasion from the 250 hour program guys. "disclaimer"--im not knocking low timers/flight programs here. Just always ask for a ride if you want to jumpseat and dont confuse jumpseating with nonreving as someone previously mentioned.
