We recently flew from Sydney to Auckland on LATAM Airlines Boeing 787-9 on their Business Class. The flight left mid morning and arrived in the evening and was a quick three hours!
As a Business Class passenger, we were entitled to priority security and boarding, as we had already checked in on our flight from Adelaide to Sydney. This made the process much quicker, and we managed to get through security efficiently.
Being a codeshare partner of Qantas, we were able to relax in the Qantas International Lounge before our departure which provided a comfortable start to our journey.
