A new consumer survey says that customer satisfaction with domestic airlines is improving, but we have our doubts. The University of Michigan's new American Customer Satisfaction Index reports that customer happiness is on the rise, but that happiness might only be superficial and short-lived.

"Airlines are creating more satisfied passengers, but the….data suggests this won't last for long." Claes Fornell, founder of the index, said in a statement. "Airlines are already beginning to charge higher fares. Flights are becoming more crowded, and the increasing number of carry-ons could lead to cabin congestion and delays."

Not only that, there have also been a couple of highly publicized, very unsatisfied customers of late, namely a sleeping woman who was locked inside a flight hours after it landed and two children who were accidentally sent to the wrong cities. Worst of all, Kim Kardashian just had a grueling flight back from the Bahamas, where she was taking pics with Justin Bieber. Thankfully, she had twitter to express her exasperation: "After waiting a hour on the runway...they tell me my bags didn't make it and are lost!!!! I want to cry :-(."

Per usual, Southwest tops the customer satisfaction rankings, with respondents saying the airline is a good value (you get to check two piece of baggage, gratis) and that it has the friendliest flight attendants (despite the fact that they sometimes wear culottes). Predictably, extra fees annoy passengers, especially for things like pillows and blankets, less so for things like booze and even extra legroom. In the food rankings, Delta/Northwest were voted the worst, but, honestly, we can't remember the last time were offered free food on a domestic flight to begin with, so why bother.
