Hi,

I'm about to book PVG-HKG-PVG flights in Y at KA website and I wonder, how can I select seats? I'm BAEC silver (OW sapphire) and I entered my BA card's number, so such selection should be available for me. Unfortunately, all seats are unavailable. There're only two exit row seats available for extra charge. Should I contact them after booking?

EDIT:
OK, I know the answer. It's possible to select seat after the payment, in "Manage my booking".
