Guys, I'm very excited about the prospect of my first flight deck visit in many years during an upcoming visit to Italy and Greece. I've managed with some luck to coordinate plans with a close friend who flies MD11s for KLM (F/O). He will be flying my wife and I on the return segment from AMS to SFO. What are the chances of riding in the jumpseat these days out of Europe? Is this now banned or does the Captain have some discretion? Of course I'm shooting for an ride up front during T/O which would be my first. We'll be flying business on upgrades so not all is lost in terms of enjoyment /comfort. Thanks in advance for your insight.
