If you haven't already, check SeatGuru:

It suggests that upstairs the front row (24) has a bulkhead limiting legroom (though more knee room).. but 35 looks OK. Though apparently 35 is a bit of a thoroughfare and theres no storage so that can affect the value.
Having said that.. these seat maps are not perfect and sometimes miss out on things like TV in arm rest (problem for me because I am quite wide, for example). Can be good to try and find a user comment about them on the side.


I've just booked onto 33J for QF1 DXB-LHR on Sunday. Setup a seat alert through expertflyer.com but it opened up at T-80 which is fairly well known. With Plat, maybe you won't even have to wait that long, not sure.
The other ones people often like are 71E and 80A/K... though I think you have to pay an extra charge.. not sure if that's waived for Plat or not.
