The share that breaks connections
Across 7.05 million domestic flights, 77.4% arrived inside the Department of Transportation's 15-minute window. The flights that missed it were late by 73 minutes on average, and 8.2% of all arrivals landed a full hour or more behind schedule. That last figure is the one that ends trips.
Among the majors, Delta Air Lines led at 80.9% and JetBlue Airways trailed at 72.4%. Among large airports, Salt Lake City ran best at 84.6% and Chicago worst at 70.8%. Neither ranking transfers cleanly to a single route, which is why this site scores routes one at a time.

The twelve highest-volume routes in the data, each with its own grade. Volume is not quality: some of the busiest routes in the country are also among the least punctual, because they connect the airports where congestion is worst.

Chicago: O'Hare against Midway, by the numbers
Chicago O'Hare International runs 70.8% on time and Chicago Midway International 75.6%. The smaller airport wins on paper. Whether it wins for your trip is a different question.

Washington DC has three airports. The data says they are not equivalent.
Ronald Reagan Washington National runs 72.8% on time, Washington Dulles International 80.3%, Baltimore/Washington International Thurgood Marshall 77.3%. The one closest to the city is not automatically the right answer.

What this is
Statistics, not status
Every figure here is recomputed from the Bureau of Transportation Statistics on-time performance database, the same flight-level filings the DOT publishes each month. Nothing is estimated, modelled or bought from a third party. The methodology page states the definitions, the thresholds and the limitations in full.
This site is not a flight tracker and will not become one. It answers a narrower question: over the last 12 months, how often did this route, this airport or this airline actually deliver the schedule it sold. The one live exception is airport-level FAA status, which is on its own page and clearly separated from the historical figures.
