When to Book for Lowest Prices

Book 35–45 days before departure for 31% cheaper fares on this route, per Expedia’s 2025 analysis. March is the cheapest month at $227 avg (vs $310 in December), while July sees 22% price spikes due to hurricane season. Eurostat 2025 data shows 62% of Caribbean leisure travelers book within 35–45 days of departure, avoiding peak pricing.

Watch Out For These Hidden Fees

LIAT (5J) charges $45 for a carry-on bag—commonly missed in search results. I paid $249 for AA on March 15, 2024, only to be charged $18 at check-in for a 20kg checked bag not listed in the base fare. Always verify baggage allowances: JetBlue includes carry-on, but LIAT’s fee is added at checkout.

Logistics: Airport Codes & Transit

Fly into Antigua’s V.C. Bird International (ANU) from JFK. Transfer from ANU to St. John’s city center takes 15 minutes ($12 taxi) or 20 minutes via the #1 bus ($2.50). For cheaper alternatives, compare Jamaica (SXM) flights—JFK→SXM averages $258 in March, $31 more than ANU.
