Thank you pandaperth!
I’ve played around some more with the ideas you gave me.
I’m torn between getting two more business class flights to Doha at the end of our ticket that we can use later in the year after our main trip to Fiji and New Zealand or going with a far cheaper fare that originates in Oslo.
I want to avoid BA and Heathrow because it is a hub of delays and cancellations which we do not want to risk as the main trip has fixed dates.
Not planning on any AA or BA flights so I might just have to book online at Oneworld and suffer the consequences of a ticket through Qantas.
