I probably wrote a trip report, but way back in like 2009 or something, I booked the Omaha to somewhere in Wisconsin loophole that took you from Omaha to Sacramento, to Portland, and to wisconsin, combined with sleeper tickets to and from Chicago and coach tickets to the loophole points.
Whelp, the zephyr got cancelled so customer service in Chicago put me on the Chief in sleeper the whole way and refunded the coach tickets. So I rode in sleeper to LAX, boarded the Starlight, and they cancelled the builder; I was friendly with a forum member who worked for Amtrak at the time, and he helped me get placed in a Seattle hotel on Amtraks dime. I rode that, explained to the conductor that I was really going to Chicago, and he told me to just ride my roomette the rest of the way and didn’t punch my coach ticket, which I got a refund on.
Fun.
