Greetings. I'm looking for feedback from anyone who has flown in the Duo seats that Air France offers. The information on their website is basic and I'm trying to understand the setup. I understand that it's 2 seats in the row at the back instead of 3 but are they configured the way they appear to be in the diagram — 1 window and 1 aisle with a gap between where the 3d seat would have been? I'm trying to decide if it's worth the upcharge.
