Question on EK load: I check in roughly 12 hours from now. Overnight it seems like the seats were blocked - though expert flyer says occupied and done in a weird way. Is this normal or should I rush to buy a seat? Flight load was about 50% in economy as of yesterday. Or is this just preallocated seating? Fare class on Expert Flyer shows this: F4 A0 J7 C7 I0 O0 H0 Y9 E9 R9 W9 M9 B9 U9 K9 Q9 L9 T9 V9 X9
