I was listening to a podcast today by Nader Kabbani, director of research at the Brookings Doha Center and a senior fellow in Global Economy and Development. He provided a background on the Qatar-Gulf crisis, which has gone on for three months, and outlined its social, economic, and political implications.
He noted that Qatar has shifted its air and land routes, and although it can take longer to get from A to B the difference is not significant. Flying to Europe and Asia takes about 20 minutes longer, while to Africa it can take longer.
