Hawaiian Airlines Carry-On Rules & Bag Size 2026

Hawaiian Airlines is Hawaii's flagship carrier, connecting the Hawaiian Islands to mainland US cities, Japan, South Korea, Australia, New Zealand, and American Samoa. One of the most important things to know about Hawaiian Airlines is that its published carry-on size limit is significantly smaller than most carriers — particularly the depth restriction of just 17 cm (6.5 inches). This guide explains why, what bags actually fit, and how to navigate Hawaiian's carry-on rules for both inter-island and transpacific routes.

Hawaiian Airlines Carry-On Allowance at a Glance

Cabin / Fare	Carry-On Bag	Personal Item	Weight Limit
Main Cabin (Economy)	45 × 35 × 17 cm	Under-seat item	None published
Extra Comfort	45 × 35 × 17 cm	Under-seat item	None published
First Class	45 × 35 × 17 cm	Under-seat item	None published

Hawaiian Airlines does not publish a carry-on weight limit. This is relatively unusual among international carriers. While there is no stated maximum, bags must fit in the overhead bin within the published dimensions.

Carry-On Dimensions in Centimetres and Inches

Measurement	Centimetres	Inches
Length	45 cm	17.7 in
Width	35 cm	13.8 in
Depth	17 cm	6.5 in

The Depth Problem

The 17 cm (6.5 inch) depth is the critical measurement. This is dramatically narrower than what most airlines permit:

Airline	Carry-On Depth
Hawaiian Airlines	17 cm (6.5 in)
Southwest Airlines	25 cm (10 in)
United Airlines	22 cm (9 in)
Delta Air Lines	22 cm (9 in)
American Airlines	22 cm (9 in)

A standard 20-inch carry-on spinner suitcase is typically 25–28 cm deep and will not fit within Hawaiian's 17 cm depth limit. Many travellers report that the published limit is not strictly enforced on all flights, but the official policy is 17 cm depth maximum.

In practice, Hawaiian Airlines' overhead bins do accommodate larger bags on certain aircraft. The A330 (used on transpacific routes) and the A321neo have bins that can physically hold standard carry-on bags. The published limit appears conservative relative to actual bin dimensions — but you cannot rely on non-enforcement as a strategy.

Personal Item Policy

All Hawaiian Airlines passengers may bring one personal item in addition to their carry-on:

• Placement: Under the seat in front of you
• Weight: No published weight limit
• No published maximum size — must fit under the seat
• Examples: Laptop bag, handbag, backpack, camera bag

The personal item has no published size or weight limit, which gives significant flexibility. A laptop backpack or a medium-sized camera bag placed under the seat gives you additional packing capacity beyond the carry-on.

Fare Types and Carry-On Inclusion

Hawaiian Airlines operates several fare classes:

Main Cabin Basic

The Main Cabin Basic fare is the lowest-priced Economy option and may have restrictions on overhead carry-on access on some routes. Verify at the time of booking. On inter-island flights, Main Cabin Basic typically includes a carry-on bag.

Main Cabin

Standard Main Cabin Economy includes one carry-on and one personal item. This is the default experience for most leisure travellers.

Extra Comfort

Extra Comfort seats provide additional legroom and include the standard carry-on allowance plus priority boarding, which helps with overhead bin access.

First Class

Hawaiian Airlines First Class passengers receive the same carry-on size limit but benefit from priority boarding and often a larger first-class overhead bin area.

Inter-Island Flights

Hawaiian Airlines operates a busy inter-island network connecting Honolulu (HNL), Maui (OGG), Kauai (LIH), Kona (KOA), and Hilo (ITO). On inter-island flights:

• Aircraft include the Boeing 717-200 and Airbus A321neo
• The Boeing 717 has narrower overhead bins than wide-body aircraft
• On the 717, the 17 cm depth restriction is more likely to actually matter in practice
• Inter-island flights are short (30–50 minutes) with quick boarding and deboarding

For inter-island travel, a small soft-sided bag or a personal item may be the most practical approach.

Transpacific and International Flights

Hawaiian Airlines operates transpacific routes from Honolulu to:

• Los Angeles (LAX), San Francisco (SFO), Seattle (SEA), Portland (PDX), Las Vegas (LAS), New York (JFK)
• Tokyo (HND, NRT), Osaka (KIX), Fukuoka (FUK)
• Sydney (SYD), Auckland (AKL)
• Pago Pago (PPG)

On transpacific routes, Airbus A330-200 aircraft are used. The A330's overhead bins are physically larger and can accommodate standard-sized cabin bags. Enforcement of the 17 cm depth limit is less systematic on these routes, but the policy remains in place.

No Published Weight Limit: What This Means

Hawaiian Airlines does not publish a carry-on weight limit, which sets it apart from most international carriers. In practice:

• Flight attendants or gate agents may ask you to check a bag if it is clearly very heavy or creates a safety risk for overhead bin operation
• There is no standard weighing at check-in or the gate for carry-on bags
• The constraint is the size limit (particularly the 17 cm depth), not weight
• A heavy personal item (under the seat) is generally unchallenged

For passengers used to airlines with strict 7–10 kg limits, Hawaiian's lack of a weight limit is a welcome change, but the dimension limit more than compensates as a constraint.

Tips for Hawaiian Airlines Passengers

Choose a soft-sided bag that compresses. Given the 17 cm depth restriction, a soft-sided bag that can be compressed or flattened is more likely to fit than a rigid hard-shell suitcase. Backpacks and soft duffels in the 35–40 L range often work well within these dimensions.

Use the personal item strategically for heavy items. No published weight limit means you can pack your laptop, camera, and heavy shoes in the personal item under the seat without restriction. This takes pressure off the carry-on.

Board early on inter-island flights. Overhead bins on the Boeing 717 fill quickly. If you are in the later boarding group, your carry-on may need to be gate-checked on busy inter-island flights.

Verify the latest dimensions before packing. Hawaiian Airlines' carry-on policy and its practical enforcement have been inconsistent over time. Check the current dimensions on Hawaiian's website before your trip, especially if you last flew them several years ago.

HawaiianMiles status provides priority boarding. Pualani Gold and Pualani Platinum members (and qualifying credit card holders) receive priority boarding. On any flight where overhead bin space is a concern, priority boarding is the most valuable benefit for carry-on travellers.

Security and Restricted Items

Hawaiian Airlines flights operate under TSA security rules for US domestic flights and relevant international security frameworks for international routes:

• Liquids (3-1-1 rule): 3.4 oz (100 ml) per container, 1 quart (1 litre) transparent bag, 1 bag per passenger
• Lithium batteries: Spare batteries must travel in carry-on only; power banks are carry-on only
• Agricultural inspection on arrival in Hawaii: Hawaii has strict agricultural rules — fresh fruits, vegetables, and plant material may be confiscated by HDOA inspectors on arrival in the islands, even if carried from the US mainland

The agricultural inspection is not a security issue but is often surprising to first-time visitors to Hawaii. Items that pass TSA may be confiscated by agriculture inspectors.

The Bottom Line

Hawaiian Airlines' published carry-on limit of 45 × 35 × 17 cm — particularly the 17 cm depth — is the most restrictive of any major US carrier. In practice, enforcement varies by aircraft type and route, with transpacific A330 flights being more accommodating than inter-island 717 services. Plan for the published limit, use a soft-sided or compressible bag, and take advantage of the absent weight limit by loading up your personal item with heavier items. Board early whenever possible to secure bin space on busy routes.
