I booked award tickets (AA) on JAL from ORD-NRT. On expertflyer, it shows row 5 seats A and C open. The only seats blocked on row 5 are H and K. However, when I selected seats, A and C are also shown as blocked in addition to H and K. When I called the plat desk at AA, they said they cannot select A and C either. What does this mean? Can I call JAL to select these seats, or is there some other process to obtain these seats, or is expertflyer just not showing correct info?
