Thanks.

This is what I've got for my outbound flight: F4 A4 J7 C7 I7 O7 P0 Y9 E9 R9 W9 M9 B9 U9 K9 H9 Q9 L9 T9 V9 X9

About 76% of the seats in Y are still available for selection. If I assume that most people do select their seats when they book and taking into account the fact that the flight is less than one month away, I would say that most likely it will be more on the empty side, at = or <50%.
