Its only in recent years that AA
and US have introduced nonstop service out of BOS
to caribbean and mexican beach destinations. For years, AA
simply owned the US-caribbean market and found it very easy and profitable to route all passengers via their MIA
hubs and/or sometimes via their JFK
gateway. With the downturn in business traffic, AA
and other airlines have renewed their interest in serving beach/resort destinations, thus, we are seeing lots of new nonstop services to the islands, Cancun, and some cities on the mexican riviera.
As for BOS
, there probably is a market for a weekend nonstop service with an A320 or 757 sized aircraft...give the airlines a bit of time, maybe in the coming years a flight will be introduced, until then, you will have to transit a hub city.
