With my lot, if the seat is stuck in the recline position on the 320 it can't be used and the row behind it is to be blocked off as well.
That should be a no-brainer on any airline.
If I was sitting in a row behind a seat that was stuck in recline for takeoff or landing and the crew wouldn't/couldn't move me, I'd offload myself rather than fly.
Perhaps the author of post #5 could identify his carrier so we know who to avoid.
