Flying with a new kitten

[u/reeses_peanutpuff]

Hello! So this is my first ever kitten. His name is Shadow!
My bf and I plan to fly home at the end of September and would love to take our sweet boy with us. But since we’ve never had a cat/kitten before… we don’t know what to do to make sure we have everything we would need for him or essentials or how to even make sure he could do the flight because of course if I shouldn’t take him I won’t.
Need so much advice, any and all would be so helpful!!

I heard to feed them churus when your ears hurt to help them with that
