Knowledge expansion:

Airline fares are generally divided into first class, business class, economy class and economy class. Every cabin is treated differently! Special class seats and economy class enjoy the same treatment, both of which are normal seats! Business class enjoys semi-reclining seats, and the highest price of first class is also the highest, which is about 1.5 times the normal economy class price.

Each cabin is divided into different cabin codes according to normal fares and various special preferential fares.

The first type of code is generally F and A; Business class codes are generally C, D, etc. Economy class codes, such as: some routes are divided into five codes: Y, M, L, K and T, which represent different fares and different seats. Airlines in the world generally define and use these letters as the cabin code itself, and there is no uniform regulation on the cabin code. Passengers can use the specified price as long as they reserve the specified space.
