If your booking includes layover with a connecting flight, then you might need to claim and re-check your bags.
To be certain about baggage transfers on your itinerary, you'll need to reach out to the airline directly before your departure. It's also advised to verify this information with an airline agent at the airport check-in counter, and check that your baggage tags have the final destination airport printed on them.
Some itineraries include multiple airlines that may not have a baggage partnership and you may need to claim and re-check your bags. While rare, the connecting airline may even require you to pay an additional fee upon re-checking a bag.
