Only a lowly and undeserving Gold for now but just curious about the automatic seat blocking. If you go into a reservation on line and select a seat using the reservation/seating app, if they "block" the seat next to the one that you select, it just shows up as "unavailable", just as if the seat were occupied, correct? So there is no real way to check to see whether indeed the seat next to you has actually been blocked on line, other than to try moving to see if both your old seat and the one next to it become "available"?
