Competitive routes between major hubs like New York and London or Singapore and Dubai will be cheaper due to the fact that there are usually several airlines that are competing to make your business. When you are in need of a luxurious holiday on the cheapest business class destinations, you may emphasize on the lowest business class travel spots where you can save colossal amounts of money. The reason these lower fares come about is due to the rise in competition that forces the carriers to reduce the price in order to retain a share in the market.
