Sigh....never mind. I was just assuming that since a) WN is the end-all, be-all pinnacle of airline operations, and b) WN made a mistake by serving BOS, it would only logically follow that all other airlines should abandon BOS because it's such a poor business decision.
I'm sorry you will have to deal with mini-jets for the foreseeable future due to the needs and preferences of so many other travelers, and the profitability that those planes and routes provide to the airlines that use them.
Clearly, any perspective other than your own, even when based on empirical fact, will never be valid enough for your discerning mind.
