Air Sunshine allows full-paying passengers a free baggage allowance of 40 lbs total. Cabin carry-on space is extremely limited due to small commuter aircraft one personal item fitting under the forward seat is standard. Excess weight is charged per pound. Flights to/from St. Maarten (SXM) carry an additional $25 checked bag service fee.

Flying between Caribbean islands on a small commuter aircraft is a different experience from boarding a wide-body jet at a major hub. Air Sunshine operates regional feeder aircraft the Cessna 402, Beechcraft 1900, and Saab 340 connecting destinations like San Juan, St. Thomas, Tortola, Virgin Gorda, and Saint Maarten. Every pound on these planes matters for safety and balance.

That’s not a figure of speech. Air Sunshine staff actually weigh passengers and bags together at check-in to calculate payload. Overpacking doesn’t just cost you money it can put your bags on a later flight entirely.

What Is Air Sunshine’s Standard Baggage Allowance?

Air Sunshine’s standard free baggage allowance for full-paying passengers is 40 lbs (approximately 18 kg) total per ticketed traveler. This combined weight limit covers all luggage checked into the aircraft hold. The precise allowance can shift based on the fare type, route, and flight payload availability on the day of travel.

Air Sunshine operates only one cabin class Economy so there are no premium or business-class baggage upgrades available. Every passenger is subject to the same base rules, adjusted only by fare type and individual flight payload limits.

Key point: Unlike major carriers, Air Sunshine does not guarantee bag space for a fixed fee. Aircraft payload limits are enforced dynamically, which means a bag accepted on one flight might be deferred on another.

What Are the Air Sunshine Carry-On Rules?

Air Sunshine permits one personal item in the cabin, provided it fits completely under the forward seat. Traditional wheeled carry-on bags do not fit in the cabins of Cessna 402 or Saab 340 aircraft and are routinely gate-checked at the tarmac before boarding.

This is one of the most misunderstood aspects of flying Air Sunshine and one of the most common sources of frustration. Passengers who assume they can bring a standard roller bag into the cabin will find it taken by ground staff at the aircraft steps and stowed in an exterior wing locker or nose compartment instead.

Use a soft-sided backpack or tote as your “carry-on.” Flexible bags compress to fit under seats and into exterior compartments far more easily than rigid shells.

What Are the Air Sunshine Checked Baggage Limits?

Air Sunshine’s checked baggage limit is typically 40 lbs total for standard economy fares, with the base range varying between 30 and 50 lbs depending on the route and fare class purchased. Bags are weighed at the counter alongside passenger weights to balance the aircraft.

Real-world example: A passenger flying San Juan (SJU) to Tortola (EIS) with two checked bags totaling 55 lbs would exceed the standard 40 lb allowance by 15 lbs. Those 15 lbs would be charged at the per-pound excess rate, plus a route-based fee for the second bag.

What Are the Air Sunshine Baggage Fees?

Air Sunshine charges excess baggage on a per-pound rate rather than the flat-fee tiers used by most major carriers. This means costs accumulate incrementally for every pound over your allowance there’s no single overweight fee that caps the charge.

• Excess weight: Charged per pound above the ticketed limit; exact rate varies by route
• 2nd checked bag: Route-based fee; subject to space availability
• St. Maarten (SXM) service charge: $25 per checked bag for all flights arriving or departing SXM
• Standby baggage: Bags deferred to a later flight; standard excess fees still apply
• Oversized items: Flat fee or per-pound rate; must physically clear aircraft compartment doors

Why per-pound pricing matters: A traveler 10 lbs over their limit pays proportionally less than one who is 30 lbs over but there’s no threshold to “lock in” a lower rate. Weigh your bags at home before you travel.

Note: Alliance-based perks (Star Alliance, Oneworld, SkyTeam) and co-branded airline credit card free-bag benefits do not apply to Air Sunshine flights. The airline is an independent commuter carrier.

How Does the Air Sunshine Excess Baggage Policy Work?

Air Sunshine’s excess baggage policy is stricter than most regional carriers because small commuter aircraft have legally defined maximum takeoff weights. When a flight approaches its gross weight limit, bags not passengers get left behind.

• Per-pound fee structure: Assessed on total weight above the ticketed allowance
• Maximum single-bag weight: Bags over 70 lbs (31.7 kg) may be refused or required to be repacked into lighter containers
• Standby baggage: If total cargo and passenger weight exceeds legal limits, excess bags are deferred to the next available Air Sunshine flight
• Hot weather impact: High Caribbean temperatures reduce air density, which lowers maximum takeoff weight meaning stricter enforcement on hot afternoons

Edge case: If your bags are put on standby, they are NOT guaranteed to arrive on the same day. Pack medication, travel documents, chargers, and any essentials in your personal item.

What Are the Rules for Special Items on Air Sunshine Flights?

Air Sunshine accommodates several categories of special baggage, though physical constraints of commuter aircraft compartments impose real limitations.

• Strollers and car seats: Accepted; compact folding strollers can be gate-checked at the aircraft steps
• Wheelchairs and mobility aids: Permitted with advance notice; motorized or battery-powered devices require prior airline approval
• CPAP machines: Allowed in the cabin as a medical device
• Scuba gear and golf bags: Accepted if total weight permits; confirm dimensions in advance
• Surfboards: May be restricted on Cessna 402 flights due to small cargo door openings
• Musical instruments: Small instruments in soft cases may fit under the seat; larger instruments require an extra seat purchase or cargo hold placement
• Pets: Small pets in approved soft carriers permitted on select routes with advance reservations; space is extremely limited

Pro tip: Call Air Sunshine directly before travel if you’re bringing any oversized, motorized, or unusual item. The cargo compartment dimensions on a Cessna 402 are significantly smaller than what passengers typically encounter on commercial jets.

What Is Air Sunshine’s Luggage Policy by Aircraft Type?

Understanding which aircraft serves your route changes how you should pack. Air Sunshine operates three main aircraft types, each with different storage configurations.

Cessna 402 flights impose the tightest restrictions. There are no overhead bins every bag beyond your under-seat personal item goes into external compartments. Saab 340 flights offer slightly more flexibility, but are still far more constrained than standard commercial aircraft.

What Should You Do if Your Air Sunshine Baggage Is Lost or Delayed?

Air Sunshine is a small carrier operating short regional hops, which means most baggage issues are resolvable quickly. If your bag is delayed, it has likely been deferred to a standby flight rather than lost.

• Report immediately: File a baggage report at the airline counter before leaving the airport
• Standby bags: Ask staff for the next available departure that your bags are scheduled on
• Lost bags: Contact Air Sunshine’s customer service directly; retain all baggage claim tags
• Damaged bags: Document damage with photos at the airport and report before leaving
• Valuables: Air Sunshine, like most carriers, does not accept liability for valuables (jewelry, electronics, documents) packed in checked baggage

Note on check-in timing: Passengers must check in at least 90 minutes before departure. Arriving late significantly increases the chance that bags are weighed against a flight that’s already near payload capacity.

Pre-Flight Baggage Checklist for Air Sunshine Passengers

Follow these steps to avoid unexpected fees, deferred bags, or problems at the counter:

• Weigh every bag at home before heading to the airport per-pound fees add up fast
• Use soft-sided luggage: duffel bags and soft totes load into Cessna wing lockers far more easily than hard-shell cases
• Pack essentials in your personal item: medication, passport, phone charger, and a change of clothes, in case checked bags are deferred
• Arrive at least 90 minutes early: manual passenger and bag weigh-ins take additional time at island airports
• Check route-specific fees before you book: the $25 SXM service charge applies both ways, so a round trip through Saint Maarten adds $50 per bag
• Call ahead for special items: confirm compartment clearance for sports gear, instruments, or mobility devices

Key Takeaways: What Every Air Sunshine Traveler Should Know
