Going to Greece on Sat, went to enter API yesterday says I have to do it at airport on day of departure. Panicking now as all my info says if API not complete, then won't be allowed to travel. Also now worried me and daughters won't be sitting together on plane, but have no option to do anything about seats either! The seat thing not end of the world, children 12 and 13 so can cope, but am terrified of being turned away at airport, so can't enjoy run up to hol!
