I am sorry if this has been answered elsewhere but I couldn't find anything.
Basically I am wondering if I pay to choose a seat, can I later pay the difference to choose a more expensive seat?
I am blue and want a window seat in WTP on the A380, but I really want a bulkhead window seat where the bassinets are, but they aren't available for purchase until 5 days prior to departure?
Is it possible to pay to secure any window seat now, and later pay the extra to move up to a bulkhead window seat if they become available, rather than simply wait until five days out only to find
all the window seats are gone.
