Traveling with a PS5, any recommendations?

So im flying from AZ to MO to see my brother for a week and would like to bring my PS5 so we can play during my stay. This is my first time ever flying a commercial flight so I really have no idea what TSA and all that goes with no experience.

I read that having it in a carry-on bag is the best bet to keep it safer.

If you've traveled with one, what do you recommend and how does the process work of them checking it out? I do have the original box still but thats way too big for the bag.

Thank you
