Default is INTERNATIONAL JET only: 24×16×11 inches and 51 linear inches; main-bag weight is not stated. Domestic jet table says 45 linear inches but also 24×16×11 (which sums to 51): confirm with Cayman Airways. Domestic propeller flights allow only ONE 14×14×10 inch bag up to 15 lb. The checker has no route/aircraft selector; its default result does not validate domestic travel.
The source does not say whether wheels and handles are included, so measure the full external size to be safe.
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyCheck cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Measure the packed bag and verify the operating carrier's rule.
Confirm departure-airport security rules. Cayman Airways still publishes 90 ml/3 oz wording and a 12 oz hand-sanitizer exception; do not assume that exception applies at TSA checkpoints. Current FAA guidance limits ordinary carry-on liquids there to 100 ml/3.4 oz containers. Other airports and medical exceptions require separate checks.
Source-based research; no hands-on test or specialist review claimed.

TSA checkpoint footnoteSource review: · Codex (AI source review)
Main-bag weight and wheels/handles wording are not published in the jet carry-on table. No extra cabin entitlement is inferred from Business checked baggage or route-specific excess charges. Confirm every domestic segment and aircraft before using the default checker allowance.
Rules can change. Always verify with Cayman Airways before flying.
