Be aware that on the A380:
1. Exit row seats are a bit narrower, because the TV folds into the arm-rest
2. The folding TVs are a bit smaller than all the other TVs
3. The TVs have to be moved into the armrest during takeoff, landing etc
Of course, you do get a lot more legroom. Also, some exit rows have bassinets for babies - make sure to ask for a row without a bassinet at check-in.
All JFK flights use the A380. For HKG, it depends on which flight you're on.
My Samsung Galaxy Tab S 10.5 tablet has a Sandisk 200GB MicroSDXC card and I currently have about 170 movies and my entire CD collection on there. So I probably don't need the IFE.
I'm surprised that they have bassinet mounting points in front of exit row seats. Shouldn't only be in front of the bulkhead seats?
