Just had a EK flight and was on Y on the 2 class 380.

Thought I'll get seats in the forward section of the Y lower deck.

The seats are fine but the first few rows have very limited overhead luggage storage space.

So if you really want to keep your carry on on the space above your seat on the 2 class A380 in Y , I would suggest you avoid rows 41 to 44 on the 2 class 380 in Y .

There is space for a rucksack/soft luggage etc but a standard hard shell carry on would be a struggle to fit in till around row 43 or 44 depending on the size.
