Air travel at home and abroad is generally divided into two grades: first class and economy class.

Economy class seats are located in the middle to the rear of the aircraft, which occupy 3/4 space or more of the fuselage, and the seats are tight.

First class or business class is very attractive for those who have difficulty in entering or leaving crowded seats or who can not queue up for toilets, or those who are willing to make travel more comfortable and affordable.

The seats are spacious, and passengers can play cards on the table between their seats or open their papers.

Cocktail is free and the food is more exquisite. If you want, you can also supply champagne.

The crew only takes care of 10 to 15 passengers, so every request of the passenger can be immediately satisfied.
