NYC does need more competition and as much as we would love to see CO and DL increase their equipment size on the routes it is much more beneficial to MAN to have 3 different airlines. It now opens up more of the Caribbean and South America to MAN via JFK than it did before via ORD (I think) and for all TATL passengers on the route it will keep fares down unlike the rising prices we have been seeing recently due to the duopoly.
BOS would be a very nice return. I am guessing these would both be daily?
