The most weatherproof airport: Minneapolis-St. Paul
Weather is the Achilles heel for plenty of airports. Summers in Florida mean thunderstorms. A mix of rain and snow in Northeastern airports like Newark Liberty International Airport in New Jersey mean that delays and cancellations can pile up.
Despite its northern climate, Minneapolis-St. Paul International Airport largely escapes this fate. The Twin Cities endure more than 51 inches of snow each year, according to the National Oceanic and Atmospheric Administration.
But MSP, which is No. 2 among large airports in the Journals rankings, still stands out for measures of reliability. It had the highest percentage of on-time arrivals (82.9%) and on-time departures (82.4%) among large airports. It also scored well for taxiing times in and out of the airports terminals and for the average length of departure delays.
