Alaska Airlines - 89.55%
United Airlines - 88.93%
US Airways - 86.63%
Continental Airline - 85.62%
American Airlines - 81.78%
Delta - 80.98%
Jet Blue - 78.56%
Southwest Airlines - 78.5%

A Southwest spokesman told the Chicago Sun-Times, "It's a disturbing trend, and I can assure you our guys are on it."
