I have a flight coming up to HKG using AA Miles on CX. Currently, we are booked in F in seats 1D & 2D. I called AA to try and change to 1A/2A or 1K/2K, but she said those seats are reserved for Elite Status passengers. I asked if/when those seats would open for others and she said never - I questioned and asked what if it ended up empty and she maintained I could still not get those seats. There are only 6 seats in F on that CX 777 and I would prefer a window seat. Any tips/ideas on this? I'm assuming if the seat was indeed empty the day I flew the FA would let us move, but I would rather find a way to lock in and not take the chance.
