Traveling alone in club world and am looking at seats. I'm BA Silver. What seat do you suggest for a single traveller on this aircraft 777 200. I've looked at Seat Guru but wasn't sure it was entirely accurate. I've booked 5A on out bound as I believe it has easy access without disturbing 5B and the return booked 10B 2nd cabin as it shows direct aisle access. 5B wasn't available on return.

Thanks Kindly, as I mainly fly QR or EY or BA in Premium Economy with family so not completely familiar with the seating.
