United Airlines was the most on-time among the nation's major carriers in January, according to new figures from Portland's FlightStats.com.
United’s flights arrived within 15 minutes of their scheduled times 85.37 percent of the time last month. Just behind United was SeaTac’s Alaska Airlines, on time 85.3 percent of the time in January.
Southwest Airlines was at the bottom of the list with a 62.05 percent. Southwest said it believes the data used to compile that ranking was wrong.
