Thank you so much for all the answers! Also, thank you for the idea about buying directly business! I can do the whole trip with my miles!!

I usually fly to South America and it's almost never worth it, so somehow I didn't even think of it.

Short follow.up question, which flight would have the best business experience?

• A330 SWISS – from Zurich (ZRH)
• 787 Lufthansa – from Frankfurt (FRA)
• A350 Lufthansa – from Munich (MUC)
• 767 Austrian – from Vienna (VIE)
