and i don't think juta operates that early, When we arrived in Mo-bay in Feb. I inquired with them about how late they run to Negril and back as my daughter was coming in 2 days after us and they only run until the majority of flights have come in so that averages around 6-7 pm. so i would think they start first pu in Negril somewhere around 7 am
check their website . I would just get a private driver Toby's is only about 5 or so minutes from the airport.
