I'm currently at T-23 for QF127 from SYD to HKG in Y tomorrow and I was holding out until online check-in to select my seats so I could avoid the $30 charge; it seemed like a reasonable thing to do given that the seat selection screen was showing plenty of free seats on the flight. However, when I checked in the "seat selection" screen was completely greyed out and forced me into a a seat I'm not particularly happy with. The seat purchase screen still shows plenty of window seats (which I was hoping to get) available. Has anybody had this problem before and is there anything I can do, or will I just have to roll the dice and take whatever's left when I show up at the airport?
