Pilot asked if I was going to Dallas. I told him yes. He said "let's go". We walked out to the plane. It was a Challenger. I asked if they switched out the aircraft. He said no, then he asked for my name. I told him Nile Law. He said oops, and we walked back to the FBO. Good thing I didn't get on that flight. It was going to Winnipeg! I found my OneFlight pilots. We flew back to Dallas. Great flight. Thanks!
