Carry-On Rules for Caribbean Flights: Airline Guide

Check the actual operating carrier, fare and every onward island segment. Regional aircraft can have different storage and handling conditions; an island destination alone does not create a universal smaller cabin limit.

Current Caribbean Airlines allowance

Caribbean Airlines permits one main bag up to 56×35×23 cm and 10 kg, plus one personal item up to 43×33×15 cm. This applies to every customer on all flights, including Business. Wheels and handles count; duty-free purchases fit within those two items. A separate personal-item weight or combined total is not published on the reviewed page. Confirm space and handling on the booked aircraft; do not assume an extra Business main bag or a universal gate fee.

Reviewed US-carrier allowances

American permits one 22×14×9 inch main bag plus one 18×14×8 inch personal item, including Basic Economy. Handles and wheels count; no numeric main-bag weight cap is published.

JetBlue includes one 22×14×9 inch main bag plus one 17×13×8 inch personal item on all current fares, including Blue Basic for travel from 6 September 2024. No weight limit is published; cabin space and aircraft conditions still apply.

United Basic Economy normally includes a 17×10×9 inch personal item only. Published exceptions include South America, transatlantic/transpacific itineraries and qualifying status/card benefits. Confirm the actual booking; the Caribbean label does not establish an exception.

Delta includes a main bag even in Basic Economy. Small Delta Connection aircraft can require checking the main bag; confirm the operating partner and handling conditions.

Spirit is retained as a historical record after its reported 2 May 2026 cessation of flight operations. It is not a current travel option or fare-price comparison here. Historical Spirit record.

Regional and small-aircraft segments

InterCaribbean, WINAIR, Seaborne and other operators have their own current rules. Their dimensions, weight, charges and handling are not established by Caribbean Airlines’10 kg allowance. Check the carrier before booking an island connection.

There is no universal 40×30×15 cm safe box or guarantee that a larger bag is checked free and returned at the aircraft door. Ask where it is handed over, what charges apply and where it is collected. Keep documents and necessary medicines accessible, and confirm battery handling before a bag goes into the hold. A soft bag may be convenient but must still comply when packed.

Customs and duty-free purchases

Use the official customs guidance for every destination, transit and return country. Do not apply one alcohol, tobacco, food, medicine or currency allowance to the entire region. Your nationality alone does not determine import permission, and a duty-free receipt does not guarantee acceptance at the next security or customs checkpoint.

Caribbean Airlines counts duty-free purchases within its main bag and personal item. Check cabin storage and import conditions separately.

Planning a mixed route

Weigh the complete main bag, measure protrusions and check piece count for each segment. Select the actual fare in the route checker, then confirm route, infant and aircraft exceptions that the tool cannot determine automatically. Meet every segment’s allowance rather than relying on a full-service label or supposed relaxed enforcement.
