For the 17th consecutive year, Delta Air Lines is the air carrier least likely to generate complaints.

The latest U.S. Department of Transportation Air Travel Consumer Report shows that Delta received only 0.55 complaints per 100,000 boarding passengers in 1990, the lowest ratio of complaints recorded by Delta since the agency began consumer reports."Passenger satisfaction has been the foundation of Delta's operation since we began passenger flights over 60 years ago. We have always believed that if we provide the public quality products backed by skilled and dedicated people, those products will be successful," said Whit Hawkins, Delta's executive vice president of marketing and stations.
