Next Week im flying SIN-SYD on the A388- Im currently loacted in 75K, so about in the middle of the top deck. Apparently the best location to sit- So definently go Top Deck.
The only thing, mabye its just me, is the storage space. I have flown in the last row of the T7, which means there is a rather large gap, about the same as the storage space on the A380, between the seat and the window. For me, I like to rest my pillow against the window to sleep, therefore I will be unable to do this. Then again, mabye its just me. Luckily its only a 8hr flight, so I wont be doing a huge amount of Snoozing.
