A sinkhole has caused significant delays and cancellations at LaGuardia Airport by shutting down one of its runways. Discovered during a routine morning inspection, the sinkhole has prompted warnings from the Port Authority, indicating that passengers should expect ongoing travel disruptions. Emergency crews are currently working on repairs, but the situation has already grounded hundreds of flights across the US, leading to travel chaos as the busy airport faces heightened delays, especially ahead of the Memorial Day weekend.
