Amid higher fares more delays and lost bags complaints about airlines also rise study says

WASHINGTON — AirTran and Jet Blue have taken the top spots in a national survey of airline quality.

They were followed by Southwest, Northwest and Frontier airlines. At the bottom of the list was Atlantic Southeast Airlines.

The annual Air Quality Rating survey released today found that overall the industry did a poor job last year. There were more lost bags, more bumped passengers, more consumer complaints and fewer on-time flights than in the previous year.

The rate of consumer complaints was up 60 percent. US Airways had the most complaints last year. Southwest had the fewest.
