Nope, I am not entitled to a F seat. I'm not really entitled to much actually... I travel in uniform for the headaches that it cures while traveling. Jumpseating is a privledge that I have as an airline pilot. It is free travel and we get the very last priority. I have sat in FC as a jumpseater many times but that is only after I was accommodated onboard after every passenger had a seat. Then, it is at the descretion of the crew - usually the lead FA. While I would have enjoyed the front cabin, beggars can't be choosers eh?
About the DL flight to SFO - the reason I ask is because on their website - it keeps saying there is no such flight. Hmmm...
