We are traveling with our son to Bali for over two weeks. It is over a 27 hour flight. If we bring his Nintendo Switch with us to Bali, will we have any issues getting it through customs, both ways?
No. It will be treated like a tablet so you'd take it out of your hand luggage for x-ray when going through airport security checks but that's it.
Shouldn't be a problem... just don't take a boogie board.
