I sat in EC from from JFK-TLV Monday night, and it was magical. I slept for 9 hours. Additional recline was great.
I sat in the middle section on the 747 Seat 24E (Yes a middle seat, my dad wanted an aisle and I figured I could care less)
Only complaint - two middle seats in the middle row share space under the seat in front.
Basically highly recommended and glad I don't have to pay $125 for the seat for myself or family members. Would consider doing an MR if I am close to plat again just for this benefit.
