But in theory you have this risk on a full flight anyway. What if a parent & child are moved onto your flight (for teh sake of argument because of a delayed connection) into the last two seats, but they're not together? A degree of shuffling will have to take place and could impact you wherever you end up sitting if all the planets are out of alignment etc etc.

The point I was trying to make was that yes there's a risk you could get kicked out of 64A. You could get kicked out of 62A (the seat shifters are alive and well) you could get downgraded, you could get diverted. You could get stranded in a far off country (look at what we've seen in India and Thailand of late).

Whatever happens, you're not living in a once prosperous country that now has 80% unemployment and rampant cholera...
