Flew with Cape Air twice (EIS - SJU; 2 round trips) and never experienced any problems. One bit of advice, it is a small plane so be prepared for that. I am very comfortable flying in small planes since I live in the Caribbean and fly to many of the smaller airports on business but if your not comfortable in a 9 passenger Cessna 402, I would suggest against Cape Air and opt for the ferry service between STT and STX, but if you an easy flyer go for Cape Air.
