Since the 1990s, a trend developed in which many airlines eliminated first class sections in favour of an upgraded business class. Newer business class seating is increasing adding features previously exclusive to first class such as convertible lie-flat seats, narrowing the amenities gap to an extent that first class is redundant. Furthermore, with the late 2000s recession, airlines have removed or not installed first class seating in their aircraft, as first class seats are usually double the price of business class but can take up more than twice the room, leaving business class the most expensive seats on such planes.[2] However some, such as Garuda Indonesia, have opted to reintroduce first class seating sections with new aircraft.
