While flying late this summer, I noticed while boarding that most of the passengers were frequent flyers, of the Gold, Silver, Platinum, Titanium, Molybdenum, Diamond, Sapphire, Emerald, Ruby, and Peridot varieties. They all boarded first, followed by customers of various airline alliances, followed by people who had paid $21 to follow them, followed by the ragtag rabble such as myself. My brother, who just missed out on Platinum this year, has explained that because all the airlines have merged, all their frequent flyer programs have merged as well. This has the effect of creating a permanent underclass of infrequent leisure travelers. I suppose, if there is anything to be thankful for, it is that the airline I flew did not arrange for passengers to deplane in order of rank, as I would have surely died of apoplexy.
