I have children - three of them - and I've travelled all over with them but I never allowed them to inflict their bad behaviour on others. When we travelled I prepared for it - each of them had a little backpack with a drink, a snack, a new book, colouring book, colouring pencils, cd player with a new cd with either music or a story depending on their age. I also reconciled myself to the fact that both my husband and myself would have to spend the entire flight supervising them and keeping them occupied, that's parenting! The parents of the children who kicked my seat non-stop chose not to sit with their own children, the mother was reading a magazine and the father was doing a crossword, they neither supervised their children nor provided them with ANYTHING to keep them amused - a total abdication of all responsibility!
