Most-Complained-About Airlines 2010
No. 19: Southwest Airlines
.21 complaints per 100,000 passengers
More than 100 million passengers flew Southwest last year, which makes its amazingly low number of complaints to the DOT that much more surprising. To put it in perspective, Southwest gets only a single complaint per 500,000 passengers. The Southwest staff’s famously sunny disposition may have a lot to with the airline’s No. 1 ranking three years in a row.
