Don't be under the mistaken impression that just because you're travelling on one ticket that you're safe if you miss a connection.
I recently missed a KLM to KLM connection at AMS due to a delay caused by inadequate de-icing facilities. Next flight was next day . I and many other fellow travellers were stranded overnight due to KLMs refusal to provide overnight accommodation. They just continually said that the delay was not their fault therefore they were under no obligation to accommodate us.
