Business is a Class of travel. The First benefit is that you can Check-In later at a dedicated desk (avoiding the queues).
You can then relax in the comfort of the airline's lounge where you will find complimentary drinks, snacks, newspapers and quiet. There's no rushing or queuing to board your flight. Your flight seat will usually be a cradle that reclines to a virtually horizontal position, which has legroom up to 150 cm (60in). The in-flight staff are dedicated to your cabin, and when you arrive your luggage will be among the first off the carousel.
