United wins "worst airline" four years running!
For each of 2011, 2012, 2013, and 2014, the U.S. Department of Transportation received more complaints (per passenger) against United Airlines than any other major U.S. airline (data from the Air Travel Consumer Reports, formerly here). Similarly, the independent Airline Quality Rating study continues to rank United with the lowest score (that is, the "worst"), as reported in US News as "America's Meanest Airline".
Does it come as any surprise that United is focused more on suing Untied.com rather than improving its customer service?
