Major carriers are launching a new money-making scheme that I approve of: ads on boarding passes. As the Wall Street Journal reported yesterday, Delta has already added promotional messages, coupons and destination-based travel information like weather reports to some boarding passes and at least four other airlines (Continental, United, Northwest, US Airways) have partnered with the company producing the ads and expect to roll out the new boarding passes within the year.

Sure, some people will probably decry the presence of yet more advertising images in their everyday lives, but the airlines clearly need to find new revenue streams - and this one arguably benefits some travelers - and it certainly doesn’t take anything away.
