The first class and business class flights differ greatly. The major difference between the two premium classes – business class and first class – are in the seats and service. Moreover, the differences among airlines, airplane models and routes also vary. Some of the leading airlines offer private suites to first class passengers, while those flying in business class are offered fully lie-flat beds. The food and drink offered in the two classes also vary.
First class passengers are treated a fine dining experience at the level of a Michelin-star restaurant, while business class passengers enjoy a restaurant-level dining experience. It can be said that generally first class amenities are superior when compared to business class amenities offered on international flights.
