Thanks to all for the detailed info and advice! This is very helpful in planning seating for a JFK-EZE-JFK trip that my best friend and I are taking in March to celebrate his 50th birthday.

Could someone traveling soon please share photos of the suggested across-the-aisle option for two people, e.g., the H&L combo? The same for the A&D pairing in rows 1, 3 & 5 also would be appreciated. Although I've tried to find pics online, none seem to provide a clear context of how much you might be able to see each other. Thank you in advance!
