How can a fully-booked flight that departs in 2.5 days have nearly 40% of its seats unassigned? Normally, I'd assume an aircraft change had just occurred, but I've been monitoring this flight for over a week and neither the seating chart, equipment type, nor the Y inventory has changed by more than a couple of seats.
