After reading this thread, I checked my flights online - BOS to MCO in November. Both flights had been moved, and new flight numbers appeared at the old times. So, basically, they moved my flights earlier with the same number, and gave the original time a new number, therefore freeing up an empty plane at the more popular time. Those airlines are slick.
I called and got the morning departure changed back to the original time (with new flight number) and managed to get 4 seats together - even better seats. The flight back at the original time (again, new flight number) did not have 4 seats together, so I stuck with the new time. Not a big deal, we weren't going to any of the parks the last day anyhoo. But, I will check back each day to see if seats free up on the afternoon flight. I'm sure there are alot of people swapping plans around.
The cool thing is that I could verify the itinerary changes online while I was talking on the phone and saw my old seats become available and the new seats be taken. It was very cool to be able to verify that the person on the phone was making the correct changes as I was talking to them.
Another interesting thing, they claimed that they did not have my home phone number to notify me of the changes because I made the reservations online. Actually, a disney rep made the flight arrangements (I talked to a disney rep on the phone). So, for anyone who made flight arrangements through disney, Song may not tell you if your flight has changed.
Now, to make sure the Magical Express is up to date on my new flights......
