We are just about to do this a 14 hour flight to the US. But Matilda is alot older so I guess this comes with different obstacles. Fi thats interesting what you said about the bassinet seats going up to 11kg? Matilda's not 11kg yet and they told us that they only go up to 1 year old....hmmmm maybe I'll get onto them today to check it out as we were told she was too young to have her own seat & too old to get a bassinet, but I can't imagine 14 hours with her on our laps!!
