I have a flight from São Paulo (Brazil) to Auckland (New Zealand). It's a long flight but I choose Qantas because it had the best duration for the money.
This flight was going to take 19h40, and now they changed it and it's going to take 21h10. It's not much more, but given that it's already a very long flight and I've paid for this specific flight because it took less time, do they owe me any compensation?
I could have picked another airline, I can't prove anything because fares & details have changed.
Edit - Flight information
It seems they changed the flight from Santiago to Auckland, I'm staying more time at the Santiago airport and the Santiago-Auckland flight was either delayed or overbooked, I don't know.
