Generally speaking, plane seat A stands for window position. The specific seat number can be seen on the seat map. But seat A is not necessarily a window seat, because sometimes the seat of the plane may be temporarily adjusted, so it needs to be specific. When buying a ticket, the seat number on the ticket will show whether it is by the window, such as 5A, so it must be by the window. Here a stands for the window seat on the left side of the plane.
Generally, there are window seats on the right side of the plane. According to international standards, the seat number is K, but different airlines have different naming rules for seat numbers. For example, Hainan Airlines and China Southern Airlines, the naming of aircraft seats is mainly in accordance with international practice, but China Eastern Airlines and Air China respectively use A and L to indicate the window position.
At the same time, there may be some differences in cabin coding rules due to different aircraft memories. If it is a narrow single aisle, then F stands for a window seat. If it is a wide-body model, such as Boeing 777, and there are two aisles at the same time, J, K or L are usually used to represent window seats.
The choice of plane seats needs to be decided according to your own needs. If you want to see the scenery, it is recommended to choose a window seat, but pay attention to the glare of the light. If you want to get enough rest and not be disturbed by other passengers, it is recommended to choose the front seat. If you want to get in and out easily, you can choose a seat near the aisle. You can also buy a first-class ticket if you can.
