At the time, the airline could only rebook me to fly days away (7) on the same flight # (something to do with codeshare inventory). I could rebook myself (ie pay for a one way ticket) on that flight number to fly 36 hours away, saving $ in hotel costs (and also making sure I was getting back home on time – that was holidays). I will keep you updated as to what happened. It's been 2 weeks and they usually have a 3-week turnaround time.
