Nice update! I've always been vaguely curious about American Samoa, but there's very little information about it to be found.
I hope your delays and complications are now behind you for this trip. I didn't realise that some of Air Fiji's intra-island hops were so unreliable. I thought they were a reasonably well-run airline - at least their long-haul and Australia/NZ services are fairly well regarded, especially since the recent rebrand and A330 fleet upgrade.
