Seems that when a big convention is in town, the MBTA runs special Silver Line service to the airport straight from the convention center, rather than making people carry their bags on that long walk to the nearest Silver Line stop and crowding onto a bus there.
Are you outraged? The Herald is, to the point of displacing its long-running Indian Joke of the Day series from the front page, which today features end-of-world fonts to accuse the T of stealing "all" its buses to service fat-cat conventioneers. Who, the Herald grudgingly admits, pay their fares just like rest of us - but only after the paper's crack investigative unit did some undercover surveillance:
On Friday, a Herald reporter and photographer observed people at the convention center paying regular fares to board the nonstop airport-bound Silver Line buses. The drivers did not take normal Silver Line routes or make any Silver Line stops before dropping passengers at Logan Airport. A driver said the buses provide conventioneers with rides to the airport. A bus tailed by the Herald did not follow the Silver Line’s dedicated bus route, instead driving directly to the Ted Williams Tunnel.
Ed. derail question: Why is the convention center stop so far away from the convention center?
