Mokulele Airlines will not sell a seat to a passenger who weighs more than 350 pounds. That is not fine print, it is Rule 10 of the carrier’s own Contract of Carriage. It sits right next to the numbers behind the Mokulele Airlines baggage allowance.
On a nine passenger Cessna Caravan, every pound on board gets counted, yours and your bag’s both.
Why the numbers run stricter here
Mokulele flies small Cessna Grand Caravans between the Hawaiian islands. These are not the widebody jets most baggage pages are written for.
Hawaiian Airlines can absorb a heavy suitcase without much thought. A nine seat Caravan runs a real weight and balance check on every departure.
That is why carry-on weight gets checked here more than at a major airline gate. Pack heavy and someone else’s bag gets bumped, not necessarily yours.
Carry-on and personal item limits
Mokulele allows one cabin item. It is capped at 15 pounds and roughly 14.5 by 12 by 10 inches, closer to a large backpack than a rolling suitcase.
There is no separate rolling carry-on category here. Most full size carry-on rules assume one, but this fleet does not have the room.
That single number anchors the cabin side of the Mokulele Airlines baggage allowance. Anything larger goes in the belly of the plane, planned for or not.
Checked bag size, weight, and fees
Checked bags can run up to 30 by 14.5 by 45 inches and 70 pounds. A first bag costs $30, a second costs $40, and a third costs $50 when space allows.
A bag between 51 and 70 pounds adds a $35 heavy bag fee on top of the standard charge. Sporting equipment runs a flat $35 per item.
Paired with a 15 pound cabin cap, that gap is wider here than at most carriers on the airline fee comparison pages. Anything longer than 6 feet, think fishing poles or a boxed surfboard, is not accepted at any price.
What actually happens at the gate
Travelers on Hawaii forums describe enforcement that has clearly softened over the years. One regular flyer recalled agents putting carry-ons on a scale in the past.
Several posters say that practice ended years ago on most routes. Others report boarding with bags well over the stated 15 pound line and hearing nothing about it.
A fuller flight the same week reportedly got stricter treatment. Agents seem to balance the whole aircraft, not police one bag by itself.
Treat the 15 pound line as the number you should actually meet. Do not assume it is decorative, and do not assume it is ignored either.
One legal operator, two brand names
Mokulele Airlines and Southern Airways Express are not competitors. They are also not quite separate companies.
The Contract of Carriage that governs Mokulele’s Hawaii routes is filed under Southern Airways Express, LLC. That is the same operator that flies mainland routes under the Southern Airways Express name.
Both brands sit under Surf Air Mobility and share one booking system behind the scenes. For a Hawaii trip, the figures that matter are the ones published on the Mokulele site itself.
Other small commuter carriers covering similar island routes can carry very different numbers.
Packing around the 350 pound rule
If you or a travel companion is near the 350 pound Customer of Size limit, call ahead instead of finding out at the counter. The airline states the figure as a structural fact about the aircraft, not a preference.
Its own Contract of Carriage leaves no upgrade or extra seat purchase that removes it, the way a larger jet might allow. That rule and the Mokulele Airlines baggage allowance both come from the same small cabin.
For everyone else, run your bag through a size checker before you leave, and weigh it at home. It also pays to pack light on purpose rather than find out the hard way.
The bottom line
The Mokulele Airlines baggage allowance is small by design. A 15 pound cabin item, a 70 pound checked bag, and a 350 pound passenger limit all trace back to the same small aircraft.
Gate enforcement has been inconsistent for years. Pack to the stated numbers rather than to whatever you got away with on your last trip.
