But you know of course the catch is you need to buy now. As in right now.
I would suggest buying a flight into Ft. Lauderdale that arrives before 1pm, and returns departing after 3pm. Gives you plenty of times to connect to a Caribbean Airlines or other flight nonstop out of FLL into Port of Spain (POS)! Plus leaves time on the return for the dreaded Customs line (although way less of a hassle than MIAMI INTERNATIONAL Customs).
Trinidad Carnival 2016 parade dates are February 8 & 9, 2016, so Ash Wednesday is February 10, the last day you can fly on this sale offering.
