2 hour flight with a 7 month old!

I’m going on a small chartered plane, that seats 37 people, in 2 weeks with my baby.

He’s in this phase of where he always wants to be doing something like jumping, sitting by himself, rolling around, or in his exersaucer. He gets mad when he’s held on your lap for a long period of time. I worry he’ll get mad on the plane lol, it’ll just be us 2. 😅 I’ll have no help. They put him “on-lap” on the plane.

Any tips? Tricks?
