Denver International Airport is being called one of the country's most "punctual", thanks to the latest federal figures from the Bureau of Transportation.
A new report shows more than 82 percent of flights from Denver, Salt Lake City and Chicago were on-time during the first nine months of the year.
The three airports serving New York City ranked last.
Newark Liberty International Airport in New Jersey had the worst record, with 34 percent of flights arriving late.
One-third of the planes landing at LaGuardia Airport were delayed, along with 30 percent of the flights to JFK.
New York Senator Charles Schumer calls it the first time those three have ranked last, saying they're not operating like the world-class airports they ought to be.
