I used Delta on my last trip to SXM in March. I like going through Atlanta. The only problem I has was when the Delta agent in SXM tried to charge me for my check bag. First she said it was not an international flight. So I showed her my Delta credit card which give me a first bag free and she said it was missing something. When I did not give in she checked with another agent and let the bags go free. Maybe she was new.
