Same problem for November and December
I have also been trying for my November trip. It is blacked out online too. I have called twice this week and I was told November and December "are not loaded into the reservation system yet". I was put on hold one time and she spoke to her supervisor. She came back and said they cannot make reservations yet and for me to keep calling back. I asked for an expected timeframe of when this would be resolved and she said "any day now". Don't know if it is the same issue for the end of October.
