I'm less concerned about the seat swap and more interested in why the guy decided it was a good idea to call in a private pilot and scare everyone in the process to land an airplane he's trained to land by himself. Airplane has TCAS, and if traffic avoidance was that much of an issue, an FA could do the job as well as any 150hr private pilot. Same thing with reading a checklist.
But then, that's just what went through my head when I read it and I don't have the experience or qualifications to judge the guy, so I was hoping that instead of spending 4 pages on seat swapping, we could discuss this a bit more.
