The seats that i reserved for my wife and I when managing my flights online for a holiday to NY from London have been removed and it now says they will be allocated at check in. Does anyone know why this happens? We had reserved 2 nice seats and now we could be left with not so good ones!
This subject and variations of it pop up pretty frequently.
A search will throw up more detailed responses, but generally the seats avaailable for allocation have been reserved so no further changes can be made, or perhaps your plane has changed from one config to another.
