MSNBC offers this Forbes article about airports worldwide with the worst delays. Airports in Brazil take up three of the top four spots for most delayed departures, and Beijing Capital International Airport comes in at number two. That's bad news for the crowds set to fly in and out of Beijing this summer for the Olympics.
Other airports on the list are Cairo International in Egypt and Charles de Gaulle in Paris. Looking at arrivals, Mumbai and Delhi in India take the top two spots, and La Guardia and Newark are also in the top five worst airports for arrival delays.
