I arrived home from China yesterday and found a letter from AF waiting. It was a short one were they apologized for the trouble I had, and gave me a voucher for 500 SEK (~65 USD). They didn't specify in the letter though what my trouble had been, something like "sorry for the trouble you had with your seat" would have been nicer. Oh well, I'm pleased anyway.
Thanks for all your comments. 17 flights were not so troublesome, I got used to it and had a lot of reading material with me. I got silver now and am missing 9 segments for gold, hoping to do that before christmas. But fares are so high right now with fuel surcharges etc.
