Maryland (MD) has 2 airports tracked in the Bureau of Transportation Statistics on-time performance dataset, which together handled 1,051,812 flights. Across those flights, the statewide on-time rate comes in at 78%, with 13,193 cancellations producing a 1.25% cancellation rate. The average delay when a flight runs late is 61.1 minutes. Together these numbers are the most useful summary of what air travel through Maryland airports looks like in aggregate, and they provide the baseline for comparing individual airports against each other and against national averages.
The busiest airport in Maryland is Baltimore, MD (BWI) in Baltimore, which handled 1,049,006 flights at a 78% on-time rate and an average delay of 61.0 minutes. That airport is also the most reliable in the state with a 78% on-time rate. Performance can differ sharply between a state's biggest hub and its smaller airports, so airport-level pages are the right place to dig into specifics.
Why the spread? Delays in Maryland - as everywhere in the BTS dataset, break down into five categories: late-arriving aircraft, carrier issues like maintenance and crew, National Aviation System constraints such as air traffic control and airspace congestion, weather, and security. The relative mix changes by airport and season: a small regional airport may see weather dominate, while a major hub tends to lean on late-aircraft and NAS delays. For travelers choosing flights through Maryland, the combination of a 78% statewide on-time rate, 61.1-minute average delay when late, and 1.25% cancellation rate is the concrete benchmark to weigh against specific airports and carriers.
