The price per kilogram of luggage is calculated according to the percentage of the excess, and the economy class is charged according to 65438+ 0.5% of the full fare of economy class. For example, if your ticket price is economy class 1500 yuan, the fare for overweight luggage by air will be charged at 1500* 15%, which is 22.5 yuan. If it is less than one yuan, it will be charged at one yuan. The excess baggage charge is 23 yuan. It should be noted here that the excess baggage is calculated as a percentage of the full price, not as a discount price. If it is a preferential fare, it will be charged according to the requirements of your airline.
