Business class (also known as club class or executive class) is a high travel class available on some commercial airlines and raillines. The level of accommodation in business class is higher than economy class but lower than first class. Business class passengers have a lavatory reserved for their exclusive use. Recently on airplanes, first class and economy class passengers were barred from visiting the business class cabin due to newly enforced security regulations. Business class quality, service, and comfort is continually on the rise at many airlines.
First time business class appeared was on Australian airline Qantas in 1979. On November 1, 1981, SAS introduced EuroClass with a separate cabin, dedicated check-in counters and lounges for full-fare passengers. Simultaneously, first class disappeared from their European fleet.
