We had our March 21st Seaborne flight from Beef Island to San Juan cancelled - 4 couples. Flights were booked though United and American who were only somewhat helpful.
One couple got on later flight and were able to rebook their flight to Philly. Myself and the two others got the late afternoon flight off of Beef and will overnight in San Juan.
No explanation for the cancelled flight - and if notices are coming from the US carriers, we've yet to see them.
