At the risk of inviting hate emails- kids should be banned from flights unless there is an extremely good reason.
Wasnt my choice for you to have kids, so why should i put up with them crying and bothering my journey.
Just so mummy and daddy can go somehwere nice on hoiday is not a good enough reason to ruin 7hrs of my life. Its selfish.
If you guarantee your kids dont cry, kick etc.. or have a dying relative abroad then igonre all that.
p.s. i am half inviting a nasty response, but I do feel that way when some little sht is crying for a whole flight right behind me. Also I know that wasnt the original question, but it is a pet hate so couldnt help myself.
