Indeed. Seats 39 AC (there is no B) would be the best for a couple. They also make 40C have infinite legroom (but pretty exposed to people walking up and down the plane).
These 3 are taken so what’s left is either:
- 2 seats out of the 4 in the middle 39 FG
- 2 seats on the right hand side 40 HJ (40 I is a bassinet that is currently blocked)
Don’t know if the legroom on 40 HJ is same as 39 FG and how likely we are to be moved if somebody comes with a baby and they sit the whole family there.
