Every airlines sets its own baggage allowance per route & fare. This means that depending on the option booked, checked baggage may not be included.
The usual common rule for checked baggage, when included is one piece around 23kg. However this might change from the airline thus we recommend to double check that before travelling.
In all cases a passenger is allowed to carry hand luggage, up to 8 kg. Make sure you check the specifications (dimensions & kilos) on the website of the airline you are travelling with.
