When you're hopping between the islands of Hawaii, the experience is a world away from the massive terminals and jumbo jets of the mainland. Flying with a little one on a nine-passenger Cessna Grand Caravan brings its own set of charms and challenges. The Mokulele Airlines Infant Policy is designed to be as straightforward as a day at Waikiki, but because the planes are small, there are a few weight and safety specifics you really need to know before you show up at the gate.

From Maui to Molokai, here is exactly how to navigate the skies with your infant when flying Hawaii’s favorite island hopper.

Defining an Infant: The Age Limits

The first step in any travel plan is knowing where your child fits in the fare structure. According to the Mokulele Airlines Infant Policy, a passenger is considered an infant if they are under two years of age on the date of travel.

• Age 0 to 23 Months: Your child can travel as a lap infant.

• 2nd Birthday: On the day a child turns two, FAA regulations kick in. They are now required to have their own seat and a standard ticket. If your child has a birthday during your vacation, remember that you’ll need to book a seat for them on the return leg of the trip.

Lap Infant Rules and Fees

One of the best perks of flying with a baby is the cost savings. For domestic flights within the state of Hawaii, Mokulele allows infants under two to fly free of charge as long as they sit on the lap of an adult.

The "One Per Adult" Rule

For safety reasons, only one lap infant is allowed per adult passenger (who must be 18 years or older). If you are a solo parent traveling with twins, you will be required to purchase a seat for at least one of the babies. This ensures that in the event of turbulence, every child can be safely secured.

Identification and Proof of Age

Even though your baby is flying for free, the airline needs to verify their age for the flight manifest.

• The Birth Certificate: It is highly recommended to carry a copy of your infant's birth certificate. While you might not always be asked for it, if your toddler is on the taller side and looks like they might be two, the gate agent will need proof to let them fly as a lap child.

• Check-in Fees: Mokulele is generally very accommodating, but be aware that if you provide fraudulent age information to avoid buying a seat, they may impose a fee (sometimes cited around $100) or require the purchase of a full-fare ticket on the spot.

Purchasing a Seat for Your Infant

While the lap option is free, many parents choose to buy a separate seat for their infant. This is often the more comfortable choice, especially if you have a wiggly baby or a flight longer than 30 minutes.

Using a Car Seat (CRS)

If you buy a seat for your baby, you can bring an FAA-approved car seat on board.

1. The Label: The seat must have a sticker stating it is "certified for use in motor vehicles and aircraft."

2. Fitting the Cessna: The seats on Mokulele’s Grand Caravans are narrower than those on a Boeing 737. Most car seats wider than 16 inches will struggle to fit. If your car seat is a "bulky" model, it might be worth calling the airline to check the specific dimensions of your row.

3. Window Placement: Car seats must be installed in a window seat so they don't block the aisle for other passengers.

Baggage and Gear: Strollers and Car Seats

When you're traveling with an infant, the gear list can feel endless. Mokulele makes this part easy by excluding essential baby gear from your standard baggage allowance.

• Free Check-in: You can check one stroller and one car seat free of charge. These items do not count toward your personal baggage limit.

• Gate Checking: In smaller terminals like Hana or Kapalua, you can often keep your stroller right up until you walk to the plane. The ground crew will take it from you at the aircraft and have it waiting as soon as you land.

• The Weight Limit: While the stroller is free, Mokulele has a very strict weight-and-balance culture due to the small size of the planes. If you have a massive double-stroller that weighs 50 pounds, just be aware that the crew has to manually lift it into the plane's belly pod.

Safety and Aircraft Constraints

Flying on a 9-seat Cessna is a "VIP" experience with great views, but it lacks some of the amenities of a large jet.

No Bathrooms

It’s the one thing every parent needs to hear: Mokulele planes do not have restrooms. Most inter-island hops are 20 to 45 minutes long, but when you have an infant, that can feel like an eternity. Always do a final diaper change at the terminal right before boarding.

Weight and Balance

Every pound counts on a small plane. When you check in, the agent will ask for your weight (and the baby's weight). Don't be offended! This is a standard safety procedure to ensure the pilot can balance the aircraft correctly.

Noise Protection

Small turboprop planes are much louder than commercial jets. Many parents find that infants are much calmer if they wear "baby earmuffs" or noise-canceling headphones. The engine drone can be a bit overwhelming for tiny ears.

Helpful Tips for the Flight

• Equalizing Pressure: Just like adults, babies can feel the "pop" in their ears during takeoff and landing. Feeding your baby (bottle or breast) or offering a pacifier during the ascent and descent helps them swallow and manage the pressure.

• Dress in Layers: The cabin of a small plane can get warm while sitting on the tarmac and then cool down quickly once you're at altitude. Layers are the key to a happy baby.

• Sun Protection: You’ll be flying closer to the ground with large windows. The Hawaiian sun is strong even in the cabin, so a light blanket to shield your baby’s legs from the window sun is a smart move.

The Mokulele Airlines Infant Policy makes it relatively simple for families to explore the islands together. As long as you have that birth certificate handy and your diaper bag is packed for a "no-bathroom" flight, you’re set for a beautiful journey across the Pacific.
