I'm trying to decide on an EC aisle seat in a 75H. The seat map shows rows 15, 16 and 17 in what appears to be a separate section from the other EC seats. I selected seat 16C, thinking that this separate section would be more private and quiet than in the back, but am wondering if it is better to take either 18D, where there are only 2 seats in the row and a lot of legroom, or 19C where there is even more legroom. Has anyone sat in the front EC section and can comment?
