This winter, Delta will operate more than 100 flights per week to 15 Caribbean destinations from New York (JFK), including a handful that will be new for 2018-2019.New York (JFK) to Nassau, Bahamas (NAS) – Second Daily Frequency, Begins October 1, 2018Flight NumberDepartsArrivesFrequencyDL494JFK at 1:45pmNAS at 5:10pmDailyDL799NAS at 6:00pmJFK at 9:10pmDailyNew York (JFK) to Kingston, Jamaica (KIN) – Begins December 20, 2018Flight NumberDepartsArrivesFrequencyDL2841JFK at 7:30amKIN at 11:40amDailyDL2843KIN at 8:00amJFK at 12:00pmDailyNew York (JFK) to Antigua, Antigua & Barbuda (ANU) – Begins December 22, 2018Flight NumberDepartsArrivesFrequencyDL458JFK at 8:35amANU at 1:49pmSaturdayDL459ANU at 2:50pmJFK at 6:31pmSaturdayNew York (JFK) to Port-au-Prince, Haiti (PAP) – Begins December 22, 2018Flight NumberDepartsArrivesFrequencyDL2716JFK at 8:35amPAP at 12:50pmSaturdayDL2718PAP at 1:55pmJFK at 5:55pmSaturdayDelta will soon fly from New York (JFK) to this beach in Antigua.

Delta also mentions that each flight will offer free streaming entertainment via Delta Studio, as well as entertainment on the seatback screen — particularly notable given the airline’s recent commitment to keep installing IFE displays while some carriers eliminate them.If you’ll be booking one of these routes for a winter escape, consider adding the Platinum Delta SkyMiles® Credit Card from American Express or Delta Reserve® Credit Card from American Express, each of which provides an additional 10,000 MQMs after reaching a certain level of spend.
