We had flights that were flying out near the same time as yours. We called deltas international customer care, explaining the situation, said they were aware. We were put on hold, she came back on and we're giving a credit to rebook and fly within a year. When then explained that SXM was the only place we fly, she put us back on hold, came back on a few minutes later and refunded the entire flight along with the insurance! (She was very nice)

Ruralcarrier said it exactly right! Unfortunately it is all on who you speak too! Just keep calling back.
