We are flying from LHR the end on June and Delta pulled the seat map from the reservation. How long before they will post it again? The have the seat numbers listed as four (2 Adults 2 Children) of us in the first row and my parents seperated in row 2. It looks as if my husband and I will have to be in the single seats with the kids in the middle. Unfortunately for me I frequently need a hand to hold as I am a nervous flyer!! My husband might actually enjoy his flight for once with me on the other side of the plane!

How soon before I can go in and make changes?
