Well I PM'd CO Insider with all the relevant info, hopefully he can shed some light on what exactly happened and why it happened. I am pretty sure the crew member was not working the flight and only catching a ride back but not certain.

I know seat 1E has some relevance to it but searches are hard because i cant search for less then 4 letter words. Is 1E the normal seat that is designated for air marshalls on CO?

I guess what im asking is do i try and avoid 1E on future flights? Most of my segments are paid F and this is the first time this has ever happened to me. I was moved once but to another open seat in F.

BTW: My fare class on the outbound was "D" I think it was the same on the return but the flight was so recent its not shown yet in my onepass account so i cant view it at the moment.
