When are you due to travel? I received two calls over a period of a few days starting about a week from when the aircraft I was due to travel on was changed from a 380 to a 777 for the same reason. You may well get a call from someone briefed to deal with the issue a bit closer to the time if you are still more than a week out or so. If you are already close to travel I suggest that you call in and see if you can speak to someone who is dealing with the issue rather than the first telephone rep who picks up. Good luck and please let us all know how you get on. Thanks.
