Hello, I'm very new to travelling, especially by myself. I have a 2 month trip in February from Brisbane to Australia to Rio de Janeiro Brazil all booked under the same ticket. So my first flight is domestic from Brisbane to Sydney through LATAM but operated by Qantas. When I arrive in Sydney I have a 2 hour and 30 minute layover, will I have to do all this rechecking and will it be enough time to get through immigration and security or do I have to just change terminals and not worry about anything? I feel like I do considering I'm changing from domestic to International. And will my checked luggage be transfered or will I need to recheck it?. The second flight is from Sydney to Santiago through LATAM but operated by Qantas and when I get to Santiago, I will have a 1 hour and 20 minute layover. Will I have to recheck anything here, go through immigration and security again or do I just go to my connecting flight and will my luggage just get transfered to the next flight? which I'll mention now. So the last one is a standalone LATAM Airlines group flight from Santiago to Rio de Janeiro. Are these layovers doable in any capacity or will I have to change the first flight from Brisbane to a bit earlier and the last flight from Santiago to a bit later to give me a bit more time to play with? Also will my luggage be checked to the final destination since there is a codeshare between 2 of my flights and a partnership between the airlines, I'm still basically in the same airlines? I just have so many questions and I can't stop thinking about it. Any advice would be appreciated, thanks heaps.
