DSis, DS1, DS2 and I are flying tomorrow morning. I have just checked in online to find we are split in three different bits of the airplane, with me and DS2 (a baby on my lap) in row X on the aisle, DS1 (2!) across the aisle and DSis, who has travelled to London specifically to fly with us and help with DS1, on row X-1. We booked ages ago, was it so difficult to keep us all in the same row? How do we get this fixed?
