This is simply why I just fly to St Thomas in the first place and ferry over. The possib;lity of not being able to land on a wet runway..on a Caribbean island...is just way too chancy.If the plane is delayed one way the whole schedule is thrown off and connections will be missed.Flying from STT to San Francisco I have several options if things go wrong..Miami, Charlotte, JFK, Philadelphia.I know some folks swear by the EIS..i also know others, like Geogre, whlo swear at it!!!
