MissChief - maybe your comments would have more credibility if you could get the airports name right?
Now regardless of what the reason or who made the decision etc, that is nothing short of unacceptable.
Eastern might have been counting on being able to operate a range of flights without competition rather than a selection of stand alone flights? Interesting that a number of posters refer to the commercial agreement with Eastern, although the Mayor said last week that they weren't paying for flights to come to the airport.
What's your source? The airline has at no point said so, nor has the airport?
From general observation, neither airlines or airports tend to make much fuss about dropping routes. None of the routes quoted by Graham K are available for booking on the Eastern website.
