Cons: "I missed the first segment of my flight due to an accident and traffic on the way to the airport. I was asked to pay $1200 to get on to the next flight (without any warning that my subsequent segments will be suspended) so I bought an one way to Dubai from NYC. Then my subsequent flights were all suspended and I had to buy a new set of flights for the remaining of the trip. I didn't get to take any of the flights I purchased through Kayak."
