I have purchased an Emergency exit row seat, 48H, for this 6.5 hour flight from Osaka to Singapore, on this Airbus A330-300 aircraft.
Besides the seat, it is almost a mirror flight to the outbound one. Hot towel and Singapore Sling to start, followed by an early meal service. My pre-ordered Kosher meal is better than the outbound. This leg has stir-fried chicken, smoked salmon, and a warm roll.
I watch a movie (forget the title) then manage to sleep for a couple of hours. I wake up, order a coffee and a side of Baileys, and settle into a Sherlock Holmes flick set at the end of his life post-retirement, which conveniently ends 30 mins prior to landing (which in itself is 20 mins earlier than scheduled).
