Detroit Metro airport is expanding next year, to include a shopping mall outside of security. Including, brilliantly, everyday amenities: dry cleaning.

Drop off your stuff, check-in, get on a plane. When you get back from your trip, you pick up the clothes on the way. Genius!

Other ideas for airport services: How about a drugstore, but after security? As long as we’re still limited to bringing tiny tubes of toothpaste through security, why not sell a full line of products beyond security? Even if the liquids ban gets lifted, wouldn’t a CVS or Walgreens work reasonably well in a concourse?
