Fiji Airways Nadi Tonga Business Class is part of the Bula! Fiji Hub Trip Report.
I have flown many 737s in my day. Some were better than others (see Ethiopian Business JNB-ADD: The Worst Flight Experience). Undoubtedly, the Fiji Airways flight from Nadi, Fiji to Tonga was the best. 
Here’s why:
Bula! Service
I wrote about the great service aboard Fiji Airways on my first flight from Vancouver to Nadi (see Bula! Fiji Airways Vancouver to Nadi Flight Review). That service isn’t only found on long-haul. It was also provided on this short 1.5 hour flight to Tonga. 
So Much Space
Some airlines cram in as many business class seats as possible. Fiji Airways had a total of 4. 
Food
Despite the short duration of the flight, there was great meal service. 
Fiji Water 
Cost
It only costs 12,500 Avios and $52 versus $466 to fly business (see Bus-Ted: Bula! Fiji Hub Points & Cash Summary).
Another Go Around
The Fiji Airways experience lasted a little longer than expected. Right before landing, the wind picked up and the pilot had to abort and go around one more time.
Overall
I didn’t have any luck finding business class flights on Fiji Airways for islands in the Pacific. I am glad I was able to experience it when I could.
Fiji has 737’s crammed with 12 seats in a limited space, but when they heard an alumnus from the recently crowned national champion was going to be traveling with them, they pulled seats for your segment.
That’s very kind of them. And you
