If you check a bag and have a layover, how can you ensure that your luggage is properly transferred to your connecting flight?

To ensure your checked bag is properly transferred to your connecting flight during a layover, you should confirm with the airline staff at check-in that your luggage is tagged to your final destination. Additionally, you can ask for a baggage receipt and check the tag on your bag to ensure it is labeled for the correct flight. It's also a good idea to allow enough time between flights to account for any potential delays in baggage transfer.
