Caribbean islands dominated Kayak's ranking of the Top International Deal Destinations for Under $500 for spring break this year. Trinidad and Tobago topped the list, with flight prices down 20 percent and a median airfare of $430, followed by Turks and Caicos, which currently boasts a 14 percent decrease in airfare from last year and a median airfare of $420. Saint Thomas, part of the United States Virgin Islands, rounded out Kayak's top three, with a median airfare of $461, down 14 percent from last year.
Southwest Vacations, which offers leisure vacation packages for Southwest airlines, is currently offering deals (some with savings of over $200) for resorts on Caribbean islands like Jamaica, the Dominican Republic and Aruba for departure dates beginning in mid-March.
