One more error:

"To compare, Ryanair's "cost per available seat mile" is USą 7, where Southwest's is almost double at USą 12.85. This means that Ryanair's operating costs are nearly 55% less than Southwest's."

7.0 is not 55% less than 12.85, it's ~45% less. Sheeeesh.

Also wonder about the following. Are 100% of WN's employees unionized? Gary Kelly?:

"Southwest Airlines employs significantly more people than Ryanair. More than 46,000 people across America are employed by the airline. In addition, all of these employees are represented by various unions."
