Single Runway Closures Can Bring Airports to a Standstill

Several of the world's busiest airports operate with limited runway infrastructure, leaving them vulnerable to disruptions. Airports like Mumbai's, with two intersecting runways, can only use one at a time. This means any closure of the active runway halts all operations with no fallback. In contrast, major commercial airports like Dallas/Fort Worth International Airport have multiple runways, allowing them to maintain operations during closures. The difference in infrastructure highlights the potential for significant disruptions at airports with limited redundancy.
