Also reusable window stickers are great for plane windows

I hate all things MLM but I do have several Usborne books (look inside your body, look inside construction sites, big book of things to spot, etc) and they are among my kids' most read books- in my very limited experience, they're worth the hype.

If your kiddo is into cars/vehicles, this tape and some matchbox cars were a hit. The tape comes off really easily from the tray table.

Also - we packed a "snackle" box (https://www.amazon.com/KastKing-Organizer-Removable-Dividers-10-8x7-25x1-65/dp/B07F2KSV3K/ref=sr_1_1_sspa?crid=M0P57MZGAL0C&keywords=tackle+box&qid=1667479915&qu=eyJxc2MiOiI3LjQ5IiwicXNhIjoiNi44MSIsInFzcCI6IjYuMzIifQ%3D%3D&sprefix=tackle+box%2Caps%2C62&sr=8-1-spons&psc=1) - just fill it with a bunch of snacks and they can pick/choose.
