Hi,
Not sure if your child enjoys books? For a (short by comparison) flight with DS then 10 mo we photocopied all of his books into one manageable binder. That worked great.
I wished we'd had a larger variety of snack foods, prepackaged in lots of little snack baggies so as to avoid fishing around while trying to also hold him. Also wish we had cut off food at the snack times ahead of being totally full. It broke the trip into sections by having it be time to eat more frequently than at home.
Good luck!
Polly
