Customers have several unique options to purchase when flying on long-haul or short-haul flights. This includes the cheapest option, typically referred to as economy class, as well as several upgraded seats for a more comfortable travel experience. One of these premium options is called business class. Business class upgrades typically offer larger seats with significantly more space when compared to the economy class seating options. Some airlines offer their business-class upgrades in spacious suites or with lie-flat beds. Other benefits of flying business class include improved meal service, priority check-in and boarding, and even access to airline lounges at various airports around the world.
