16+ hour flight activities

sa

So in June, we will be moving to another country. I’m looking for advice for activities, how to prevent meltdowns, how to travel with a cat, and whatever else y’all wanna give advice for a 16+hour flight with a 4 year old, a 1 year old and an 11 year old cat 🤦🏻‍♀️. I have a tablet for the 4 year old but I don’t think the battery will last. Idk what to do for the 1 year old.

Any advice on flying with an old cat would be super helpful too! TIA
