That's the one.
One of the frustrating aspects of bulkhead seats is that they are not all created equal, even on the same plane. My suspicion is that QF's are amongst the smallest in the industry, and TG's towards the other end of the scale. But I doubt any pax has ever measured them.
I particularly avoid central bulkheads because there's no way you can win there - if they have adequate space then other pax will use it as a thoroughfare. And the only way they can't do that is if you have no space !
BTW, I hope that was an internal Thailand flight to/from the beach. Otherwise .. thongs indeed in the opposite exit row !
