I was on CX502 and the flight was 95% full. Someone kindly explain why (1 day before flight) the seat inventory looked like the one below, which is definitely not what I was expecting (in terms of load factor).

J9 C9 D9 I9 Y9 B9 H9 K9 M9 HKGKIX 1635 2125 773 0
L9 V9 S9 N9 Q9 O9

Thanks for explaining!
