Very cool. I've done a couple of those in the Falcon. You'll watch the pre-flight planning process, fly for a while, listening to all the crazy radio chatter. It'll sound like a foreign language, and you'll wonder how the pilot can keep everything straight from when they're talking to him, to where they're telling him to go. You'll meet cool line people and CSRs at various FBOs, eat at various restaurants, sleep in various hotels, and realize that when a guy like me says, "I went to Albuquerque and Cincinnati today, both places look about the same from the corporate pilot's point of view. Get in touch with the pilot regarding dress code. Some guys wear suits, some just wear button-up shirts with ties, some (like us) wear slacks and polo shirts.
Have fun. It really is a cool job.
