Nadi is the second largest city in Fiji, which is also the only Fijian city in the game. The city has a very low business rating which does not exceed 100 and high tourism ratings which is generally more than 200.
The isolated location makes it a rather unpopular place to fly to. Monopoly passenger routes to large cities (eg. Los Angeles, Sydney) can make a good profit. However, due to its low business rating, jets with many business class seats are unneccesary.
