Airlines are highly disliked, and are frequently listed atop collections of the most hated companies by consumers. But, this year, it seems things are looking up a bit for the industry. Despite scores of reports about long TSA security lines causing passengers to miss flights, airline customer complaints were actually down about 12 percent in the first six months of 2016 compared to the same time last year, according to a recent report from the Department of Transportation. The DOT received 1,492 complaints in June, down 27.1 percent from 2,048 in June 2015, but up 31.6 percent from the 1,134 filed in May 2016. Specifically, there were reductions in complaints about customer service, ticketing, fares, delays, cancellations and missed connections. However, grievances about discrimination based on race, religion or national origin and treatment of disabled customers were up from last year. Overall, fares were the most commonly complained about topic. American Airlines and United Airlines received the most complaints of all U.S. carriers, while ExpressJet and Southwest Airlines saw the fewest.
