I'm surprised they haven't considered any direct flights to India from Fiji given the ancestral ties?
A350 aircraft could definitely make it.
Given the Australian market is challenging for India flights in the absence of an obvious O&D hub in India it’s difficult to see how FJ could make it work even with those ancestral ties.
That’s not an entirely accurate assumption.
Indians in Fiji and Indians in Australia are two completely different people.
Indians currently living in Australia have a lot of direct ties with their friends and family back in India. That fact coupled with a growing demand for students, tourists and skilled workers has seen Qantas commence nonstop flights to Delhi and Bengaluru, while Air India has increased their Sydney and Melbourne flights to daily, compared to pre-pandemic.
Whereas, Indians in Fiji are descendants of indentured labourers brought to work in Fiji by the British from the mid-19th Century onwards. They have very little ancestral ties to the country they originated from, and have developed a completely different Fijian Indian identity of their own. These people have mainly settled in places like Australia, NZ, Canada etc - which FJ already serves quite well.
