The report ranked the 14 largest U.S. airlines based on on-time arrivals; mishandled bags; consumer complaints; and passengers who bought tickets but were turned away because flights were overbooked.
Airline performance in 2012 was the second highest in the 23 years that Wichita State University in Kansas and Purdue University in Indiana have tracked the performance of airlines. The airline’s best year was 2011.
Besides being the overall leader, Virgin America, headquartered in Burlingame, Calif., also did the best job on baggage handling and had the second-lowest rate of passengers denied seats due to overbookings. United Airlines, whose consumer complaint rate nearly doubled last year, had the worst performance. United merged with Continental Airlines in 2010, but has experienced rough spots in integrating the operations of the two carriers.
This is the first year Virgin America, established in 2007, has been large enough to be included in the rankings. United carries roughly 18 times more passengers than Virgin America, and has 702 planes, compared to 52 for the smaller carrier.
The number of complaints consumers filed with the Department of Transportation overall surged by one-fifth last year to 11,445 complaints, up from 9,414 in 2011.
“Over the 20-some year history we’ve looked at, this is still the best time of airline performance we’ve ever seen,” said Dean Headley, a business professor at Wichita State University in Kansas, who has co-written the annual report. The best year was 2011, which was only slightly better than last year, he said.
Despite those improvements, it’s not surprising that passengers are getting grumpier, Headley said. Carriers keep shrinking the size of seats in order to squeeze more people into planes. Empty middle seats that might provide a little more room have vanished. And more people who have bought tickets are being turned away because flights are overbooked.
“The way airlines have taken 130-seat airplanes and expanded them to 150 seats to squeeze out more revenue, I think, is finally catching up with them,” he said. “People are saying, ‘Look, I don’t fit here. Do something about this.’ At some point, airlines can’t keep shrinking seats to put more people into the same tube,” said Headley.
The industry is even looking at ways to make today’s smaller-than-a-broom- closet toilets more compact, in the hope of getting a few more seats onto planes.
“I can’t imagine the uproar that making toilets smaller might generate,” Headley said, especially since passengers increasingly weigh more than they use to. Nevertheless, “Will it keep them from flying? I doubt it.”
The rate of complaints per 100,000 passengers also rose to 1.43 last year from 1.19 in 2011.
United’s 2012 ranking doesn’t reflect its experience over the past six months, in which the airline has made significant improvements in performance, company spokesman Rahsaan Johnson said.
“Customer satisfaction is up, complaints are down dramatically and we are improving our customers’ experience,” he reported in an email.
In recent years, some airlines have shifted to larger planes that can carry more people, but that hasn’t been enough to make up for an overall reduction in flights.
The rate at which passengers with tickets were denied seats because of full planes, rose to 0.97 denials per 10,000 passengers last year, compared with 0.78 in 2011.
It used to be, in cases of overbookings, that airlines usually could find a passenger who would volunteer to give up a seat in exchange for cash, a free ticket, or some other compensation, with the expectation of catching another flight later that day or the next morning. Not anymore.
“Since flights are so full, there are no seats on those next flights. So people say, ‘No, not for $500, not for $1,000,’ ” said airline industry analyst Robert W. Mann Jr.
Regional carrier SkyWest had the highest involuntary denied-boardings rate last year, 2.32 per 10,000 passengers.
But not every airline overbooks flights in an effort to keep seats full. JetBlue and VirginAmerica were the industry leaders in avoiding denied boardings, with rates of 0.01 and 0.07, respectively.
United Airlines’ consumer complaint rate was 4.24 complaints per 100,000 passengers. Southwest had the lowest rate, at 0.25. Southwest was among five airlines that lowered complaint rates last year, compared to 2011. The others were American Eagle, Delta, JetBlue and US Airways.
Consumer complaints were significantly higher in the peak summer travel months of June, July and August, when planes are especially crowded.
“As airplanes get fuller, complaints get higher, because people just don’t like to be sardines,” Mann said.
These complaints are regarded as indicators of a larger problem, since many passengers may not realize they can file complaints with the Transportation Department, which regulates airlines.
At the same time that complaints were increasing, airlines were doing a better job of getting passengers to their destinations on time.
The industry average for on-time arrival rates was 81.8 percent of flights, compared with 80 percent in 2011. Hawaiian Airlines had the best on-time performance record, 93.4 percent in 2012. ExpressJet and American Airlines had the worst records, with only 76.9 percent of their planes arriving on time last year.
The industry’s on-time performance has improved in recent years, partly due to airlines’ decisions to cut back on the number of flights.
“We’ve shown, over the 20 years of doing this, that whenever the system isn’t taxed as much — fewer flights, fewer people, fewer bags — it performs better. It’s when it reaches a critical mass that it starts to fracture,” Headley said.
Passengers appear to be checking fewer bags since the industry’s shift in 2008 to charging fees for extra bags, and they are carrying more bags onto planes when permitted, industry analysts said.
The industry’s mishandled bag rate peaked in 2007 at 7.01 mishandled bags per 1,000 passengers, and has since been declining. It was 3.07 in 2012, down from 3.35 bags the previous year.
The report’s ratings are based on statistics kept by the department, for airlines that carry at least 1 percent of the passengers who flew domestically last year.
