When I went to MBJ (Montego Bay) with BA some years ago, it was out across the briny in a 74 (can't recall which series). We bounced at Hamilton, Bermuda. The flight actually concluded at KINgston. So, on the return, we started with the hop to KIN.
If you are coast hugging to Florida, might that be ETOPS? My only trip there was an internal from EWR.
