"Passengers, airlines and our economy felt a $41 billion punch in the gut from flight delays," said Sen. Charles Schumer (D., N.Y.), chairman of the committee. "With the summer travel season being kicked off with Memorial Day, delays and the costs of those delays will only go up."
Missed connections, disrupted ground travel plans, lost pre-paid hotel reservations and missed meetings were among the factors considered for passenger costs.
Schumer, presenting the report along with committee Vice Chair Carolyn Maloney (D., N.Y.), said the cost estimate was conservative because it did not include flights canceled entirely and applied only to domestic flights.
Delays, he said, "aren't just an annoyance, they are a serious blow to our economy."
The costs to the airlines included $1.6 billion to pay for extra jet fuel. The report said there were 740 million additional gallons of jet fuel used, and calculated the cost assuming an average wholesale price of $2.15 a gallon last year.
It said that burning fuel during delays released an additional 7.1 million metric tons of carbon dioxide into the atmosphere.
The committee examined more than 10 million individual flight records from the Department of Transportation. It used DOT guidelines in setting a value of $37.60 per passenger per delay hour.
Those delays reached 320 million hours last year, about 20 percent of domestic flight time. The worst delays were experienced out of major airports in the Northeast and Midwest. Estimated minutes of departure delay per passenger were 30 minutes out of New York LaGuardia, 27 minutes out of JFK in New York, 25 minutes at Philadelphia International and 21 minutes at Chicago's O'Hare.
