First time on SQ and I'm looking forward to testing out the upper deck of the a380 as I've only flown the a380 with Emirates in Y. I am flying Y on SQ and have booked 78G but Row 81 is available. Seats D and G of 81 (middle section aisles) show no seats behind which would allow me guilt free recline. Has anyone experienced these seats? Perhaps someone has a different recommendation for seats on the upper deck in Y.
