Do you suffer on long airline flights as I do? If so, you may be interested to know about the carbon dioxide (CO2) levels in airline cabins. A few years ago I was inspired to buy a CO2 meter and take it along on some flights. The measured levels were high enough to cause discomfort among most people.

By torturing coach class passengers, airlines are able to sell wildly overpriced first class seats to people who have the money to afford escape. This is not a good situation. One possibility is for government to require minimum levels of service, for which airlines may compete with their pricing of fares. However, before leaping to regulation of that sort, let’s try just requiring disclosure of the level of service. Customers will know what they are buying at what price. Seat space is the most important thing being sold, so that ought to be the first thing disclosed.
