Passenger satisfaction with U.S. airlines remains low, according to an annual benchmarking survey, which identified uncomfortable seats and poor inflight service as major contributing factors. The American Customer Satisfaction Index (ACSI) Travel Report on airlines, hotels and Internet travel sites, released on April 22, found that overall passenger satisfaction remains unchanged from last year, with some airlines improving and others lapsing.
