Practical questions for this airline

Does every Brussels Airlines fare include checked baggage?

No. On European routes, Economy Basic and Economy Light include no checked baggage. Other fares use different piece and weight allowances; route, travel class and frequent-flyer status can also change the result, so the booking confirmation or official baggage calculator is decisive.
