If you can remember when travelers once queued to use pay phones at the airport, then communication is going old-school at Denver International Airport—with a modern twist. DIA now offers travelers free global phone calls (limits on international) from more than 200 landline phones located throughout Jeppesen Terminal and three concourses. The phones, launched in a partnership between Clear Channel Airports and RMES Communications, are equipped with 17-inch LCD screens that display 15-second digital ads and offer digital coupons.
