Probably not for a few months now. Here's the thing.....with only one flight each day, that could be an issue..unless you plan to arrive a few days prior to the cruise. Especially during the winter months. I would be very hesitant to book a flight for a cruise, out of Worcester. I did fly DirectAir to Sanford, but arrived 3 days prior to my cruise...just in case there was an issue. If there had been an issue, I could have hopped in the car and driven down in time for the cruise.
But, they may very possibly add more flights if they find the need..and that would be terrific!! That would mean that the people in the area are taking advantage of having JB here.
And if there were to be an issue, there would be addtl options for other flights.
