The industry posted declines last year in every area of the Airline Quality Rating, amid rising fuel prices, safety problems and bankruptcy filings that shut down three carriers last week alone.

The biggest change was in the rate of consumer complaints, up 60 per cent overall. The rate more than doubled at US Airways and Comair, and rose for 15 of the 16 airlines included in the study. The exception was Mesa Airlines.

On-time arrivals dropped for the fifth straight year, with more than one-quarter of all flights late, according to the survey. The rates of passengers bumped from overbooked flights and bags lost, stolen or damaged also jumped in 2007.

"The trend is bad and it does not look like it gets any better" said Dean Headley, an associate professor at Wichita State University and co-author of the study being released on Monday.

The survey results mesh with the spate of problems that have beset US carriers, starting with surging fuel costs, Headley said.

ATA, Aloha Airlines and Skybus stopped flying just last week because of financial pressures. Major airlines have slashed job and passenger amenities while adding fees for second bags, travelling with pets and booking tickets by phone.
