The Department of Transportation on Monday said the industry's on-time performance in the first six months of the year was its worst since 1995, the earliest period for which the agency has comparable data. In June, nearly a third of domestic flights on major U.S. airlines were late.
Part of the explanation for the worsening delays is that demand for air travel is rising, both on major airlines and on smaller regional carriers. In addition, the government said weather-related delays in June were up 7 percent from a year ago.
Reports of mishandled baggage and complaints filed with the government also rose.
Airline consultant Robert Mann said U.S. carriers improved their financial health in recent years by relying more on small, 40-80 seat jets that are easier to fill up and can be more profitable because there are fewer empty seats. However, this strategy also leads to more crowded skies and runways in a system "that was already saturated," Mann said.
For June, U.S. airlines' on-time arrival rate was just above 68 percent, compared with roughly 73 percent a year earlier, according to Department of Transportation data. So far in 2007, nearly 25 percent of flights on the 20 largest carriers have arrived late, the agency said.
Several daily flights — like Delta Flight 1891 From JFK to Los Angeles International — were late 100 percent of the time, reports CBS News correspondent Nancy Cordes.
The problem is most severe in the New York area — even as airlines continue to add new routes there, reports Cordes. The FAA held a town meeting in Hillburn, N.Y., last week to propose adding a second approach route to Newark to ease congestion — but residents went ballistic.
Travelers on Skywest Inc.'s Atlantic Southeast Airlines, a regional carrier for Delta Air Lines Inc., had it worst in June, as about 56 percent of flights arrived on time. AMR Corp.'s American Airlines was barely better, with an on-time arrival rate of about 58 percent. US Airways Group Inc., had an on-time rate of about 62 percent.
The airline industry blames the increased delays on a lack of a modern satellite-based air traffic control system, combined with increasing demand.
"We're not surprised by the numbers," said David Castelveter, a spokesman for the Air Transport Association, the airlines' trade group. "We have been saying for some time: It's going to get worse before it gets better."
The industry, along with the Federal Aviation Administration, has been pushing for a sweeping upgrade to the existing radar-based system, but has been caught up in an intense political battle over who will foot the bill — big airlines or users of smaller aircraft like corporate jets. Lawmakers face a Sept. 30 deadline before the current funding system expires.
Reports of lost, damaged, delayed or stolen baggage rose to 7.9 per 1,000 passengers in June, up from 6.3 per 1,000 last year. Complaints about airline service filed with the government rose 43 percent from last June.
