I had booked tickets to SXM from Sarasota leaving Saturday on Delta. When I called them they canceled my flight and waived fees. When I asked about a refund since it was obvious that commercial flights would not be able to use PJIA for a while I was told that they are on a day by day basis however if any of my flights were canceled by Delta then they would authorize a refund, which I would have to call them to initiate, otherwise it is a credit valid for 1 year from date of booking (Feb 23), not dates of travel (Sep 9-16). Seems ridiculous but I guess that's Delta's way to hold on to money as long as possible.
