I had booked and paid extra for a KLM shuttle service to Ottawa from Montreal. Because the Amsterdam flight was delayed the bus left without the passengers. I had to pay $450 to rent a car and am now arguing with KLM customer service about getting compensation. KLM has been giving me misinformation and I have to go back and forth to explain what their own rules and policies are.
