Can I always check in checked baggage?

Many airlines have introduced cheaper tickets that not include free checked baggage. It is best to check it at the stage of buying the ticket whether it includes checked baggage or how much is the baggage allowance. In the case of a journey with a change and a second flight operated by another carrier, check that the size and weight of the luggage will not exceed the permitted limits. Buying luggage online will be cheaper than at the airport ;)
