Last time I checked, two random arbitrary dates were not considered a representative sample.
Why do folks feel the need to post about how uncompetitive CO's fares are? If you're not happy with the fare, go fly someone else. Stop complaining about it.
I would like to think that CO (since they are actually in the business of selling seats and flying airplanes) does in fact have a clue how to price their own product. Just because you don't think it is so, doesn't mean they're wrong.
