I’ve had tighter connections where the luggage made it. They’re often pretty amazing. That said- I never ever check bags internationally . My personality Down there the clothes you need are so easily packable into carry on , I just don’t risk it. You can put some sunscreen into smaller containers but there will definitely be opportunity somewhere to buy sunscreen. You’ll pay more but alleviate all the stress of the “what if”. That’s my humble opinion anyway. Relax. Keep your bags with you. And buy what you need. (Sorry - not familiar with where )
