Thanks for the tips. I am guessing US citizens do not need visas in Dubai?
And yeah, the A380 is only until Dubai. I couldn't care less about the Dubai to HYD segment as it is only 3 hours. I was just curious if the A380 had any bigger toilets in Y compared to other aircrafts.
As far as Dubai, how much time should i budget for returning to the terminal. Come back 2 hours before departure of my next segment?
