Got 2 seats on DFW-HND for Aug 2025 as well (yay us!). First time on JAL business, and first time since I started appreciating these things. I got lucky on an AC flight to London way way back, but at the time I was very ignorant and didn't even get to eat all meals in flight. Anyways, our plane still has all seats available - was thinking of booking row 5. Do you know what's the difference between the first section of business class (rows 3-7) and the next one (rows 8-15)?
