Through-checking is standard when all flights are on the same ticket (or on airlines with interline agreements). Your bags are tagged at the departure airport with your final destination, and airline ground crews transfer them between aircraft at connecting points.
Through-checking availability depends on: whether flights are on the same ticket, whether the airlines have an interline or alliance agreement, and immigration/customs requirements at connecting airports. Some countries (like the US for international arrivals) require passengers to collect and recheck bags at the first port of entry regardless of airline agreements.
For business class travellers, through-checked baggage is standard on properly ticketed itineraries. BookMyBusinessClass ensures all multi-segment bookings have proper interline agreements in place for seamless baggage transfers. Business class also includes priority baggage handling, meaning your bags are among the first to appear on the carousel at your final destination.
