Miami International Airport ranks high in on-time flight performance among major US airports, but with one large caveat: federal statistics only track nonstop domestic flights.
Miami International offers more international flights than any other US airport and nearly half of the county-owned airport’s 40.5 million passengers last year came from international flights, according to Miami International officials.
Among nonstop domestic flights, Miami International ranked first in the nation in on-time performance in December, the most recent month for which statistics are available. According to the US Bureau of Transportation Statistics, 78.34% of arriving flights and 78.50% of departing flights at Miami International were on time in December, tops in both categories.
For all of 2013, Miami International ranked sixth in the nation with 81.97% of arriving flights being on-time and ranked 13th in the nation with 80.70% of departing flights on time.
American Airlines is by far Miami International’s largest carrier. In December, 80.27% of American’s arriving domestic flights were on time and 78.11% of departing flights were on time, statistics show.
For the whole year, the top five major airports in on-time arrival rate were Miami; Washington, DC; Charlotte, NC; Seattle, and Detroit. The top five in on-time departure rate were Salt Lake City; Portland, OR; Seattle; Minneapolis/St. Paul; and Washington, DC.
At Miami International, only 1.36% of arriving domestic flights and 1.35% of domestic departing flights were cancelled in December, statistics show.
