What size can my camera bag hold on the plane? Can you surpass it?

The size of luggage on the plane shall not exceed 20x40x55cm, and the weight shall not exceed 10kg.

This is determined by the size of the aircraft luggage rack, and the thickness can be slightly higher, because the current aircraft luggage rack has been expanded.

Baggage larger than this size needs to be checked, but the camera or lithium battery on the camera should be taken out and carried into the cabin. Because lithium batteries are in danger of explosion in unpressurized cargo holds.
