Business Class and Economy Class are usually joined together and separated by curtains, but Business Class offers appropriate food and beverage services and more comfortable and spacious seats. Business class passengers enjoy better seat design and legroom, as well as higher quality meals. First Class, on the other hand, is a separate cabin where passengers can flatten their seats to rest or sleep. First class also offers great entertainment such as movies and songs with complimentary cocktails, fruits, food and champagne. Moreover, first class passengers will be carefully taken care of by cabin crew and their reasonable requests will be met instantly. However, the fares of first class are quite expensive, much higher than those of business class. Therefore, there is a clear difference between business class and first class in terms of service, ambient space and price.
