Howdy - I just joined, and this is my first post. Is anyone else having this issue? I book flights, and select economy plus seats at the time of ticketing (I'm a 1K). It happens most often on UAX flights where the only economy plus seats are the bulkheads and exit row (thing E135). I am ALWAYS in 1A. Reserved several weeks in advance 72 hours, or there abouts, I am moved to the last row of economy, and my economy plus seat is occupied. Check in at T24, and the seat still shows occupied. Then, all of the sudden, 1 hour prior to departure, the seat opens up. (I keep checking the seatmap on the iPhone app because I am obsessed with sitting in that seat.) Also, all the other economy plus seats open up, and are empty (row 3, and exit rows). Is this really a system glitch? Does it happen to anyone else? Could United claim it is a 'glitch', when really they dump everyone out of those seats and block them to elites in an attempt to sell the seats at check-in then open them up to elites if when they don't sell? I am not trying to stir stuff up, or point fingers... It just seems really weird. Thanks - Glad to be here.
