I haven't flown on an AC E75 for a while and can't remember if there is a bulkhead restricting legroom between J and Y or if it's just a curtain like on the 321. How is row 12 on this bird? Does 12C have the IFE in the armrest? Is 12D a better choice due to this seat being properly aligned with the row 3 J seat? Or would rows 13-16 be better?
