BOS is a major DL market-they fly to all hubs, PTP routes, operate F/A base, Tech Ops, and had a state of the art terminal built in 2005.  WT can correct me if I'm wrong but I think in the Mullin days the plan was to make BOS a true hub.  Notably they planned to build a FIS facility in Terminal A but Massports wants/wanted all int'l arrivals in E and apparently that influenced DLs plans.
