Scenario:
I had a flight booked for my family, with all seats together. I booked it months in advance.
Unfortunately, I noticed about a week before leaving that they had inexplicably moved my seat without my permission.
After some investigation (and some lying by the airline, wrongly blaming my travel agent), I came to the correct conclusion that they had switched planes (and flight numbers) for my flight, and screwed up transferring things over. Oddly, it's the exact same airplane type with the exact same number of seats, but something just got screwed up on the transfer. So I was separated from my family. I was not notified by this. I discovered it during a routine check on my flight status about a week before travel.
After I told them that I knew this was not my travel agent's fault, they finally agreed that indeed it was an error on their part. The rep would not agree it was an "error", but admitted that indeed they changed my seat through an "automated process" that couldn't be explained.
They wanted to move us to the back of the plane (2nd to last row) but that was right by the bathroom and I didn't want that. There were no other seats together available at that point.
After I demanded they compensate me for this, they offered 10,000 frequent flier miles. I demanded 15,000, and they eventually relented and gave it to me. (I was offered an LOL 12,000 mile compromise when I threw out the 15,000 number as what I wanted, but I wouldn't budge.)
I suspect I can switch anyway because there will be one single person in my old seat, next to a young child (Ben), and he/she will probably want to switch anyway. So I think I can get back in my old seat, plus get the 15,000 miles. My new seat is by a window, so I don't think the person will mind switching, unless they hate windows (the old seat is on the aisle).
Did I do well here?
Seriously asking here... not trying to Jew-brag.
