If you book your connecting flights with KLM or our partner airlines, your transfer is protected: if you miss your connecting flight, you will be rebooked at no cost. If your connecting flights are with different airlines, your transfer is not protected. If your first flight arrives later than expected, you will have to find an alternative flight yourself. To make sure you have some protection, you can book a self-transfer flight with a travel agent. With a self-transfer flight, a travel agent will support you with rebooking if any of your flights are delayed.
