Thanks guys for the tips,
Brontide, No DH on the flight, going alone, so thats where a lot of my concern stems from.
I have bought a massive bag that i am going to use for her stuff.
Great tip for the change of clothes... We have always been in cloth, but for the plane we will use sposies, so i dont know how well the will go, as far as poo-tainment!!!

She doesnt like TV - she is very interested in people though, so hopefully we have some grandparent types nearby as she will befriend anyone!

As the flights are so cheap atm, i am just concerned that the planes will be full
