I am planning to travel from Madrid to Mexico City on IB6409, and I want to choose a seat with lots of leg rooms, I think they're called bulkhead seats, the seats that are next to the emergency exit. But since I will be traveling only with carry on and a small backpack, I was wondering if choosing this seat is the best option.
Do these seats have overhead storage for the carry on? what about the backpack, no seat in-front, so where does this go? (valuable items which I prefer to be close to me).
In the attached picture you can see the seating options from Iberia website. It costs 76$ to upgrade to the seat marked in blue. Is it a good seat?
