However, one often overlooked factor is the airport itself. A recent report by Cirium, a leading aviation analytics firm, examined the punctuality of major airports worldwide – those handling 25 million or more passengers annually – throughout 2024. The findings highlight which U.S. airports excel in on-time performance. Below, we explore the top U.S. airports that made the list. Let's get to the point!
