What is the price per extra kilo?
amin bram
There is no universal rate for an extra kilogram: each airline sets its own price list, which varies based on the route, ticket type, time of addition (online vs. at the airport), and sometimes the total weight of the luggage. However, certain trends can help you anticipate costs if you exceed the limits of your carry-on baggage or your allowance.
Understanding the cost of an extra kilogram (checked baggage)
- Adding weight online before departure is almost always cheaper than doing so at the airport
- For many low-cost airlines, the rate may be fixed per kilogram or per weight bracket
- Traditional airlines often use a checked baggage allowance (e.g., 15 kg or 23 kg) rather than a pure price per kilo
- Costs generally increase if the addition is made on the day of the flight
- Excess carry-on baggage (bulky or too heavy) may be treated as checked baggage and charged as such
