$4.50 FROM DOWNTOWN TO THE AIRPORT That shuttle service Metro’s been running from Downtown to IAH just got a whole lot cheaper — and added a few stops on the way. The Airport Direct service used to leave from the transit center at 815 Pierce St. with maybe one or 2 passengers a trip and cost $15 one-way ($10 if you could show a valid plane ticket). As of yesterday, the ride now costs $4.50, but stops also at the Main St. Square station and the Four Seasons, Hyatt, and Hilton Americas hotels before heading up the freeway. The transit agency has been losing $1.5 million a year on the every-30-minute service since it was introduced more than 2 years ago. [Houston Chronicle]
