Southeast Asia Air Travellers and Cabin-Bag Fees 2026: Why Transparent All-In Fares Beat Gate Fees

Why are cabin-bag fees a pressing issue for Southeast Asian air travellers in 2026?

Unbundling has moved from optional extras to the cabin bag itself, and regional carriers are watching.

Short-haul base fares across Southeast Asia increasingly exclude services travellers once took for granted, such as seat selection, counter check-in, phone bookings and baggage, on busy routes linking Singapore, Kuala Lumpur, Bangkok, Jakarta and Manila. In August 2026 Jetstar went further, announcing that from February 2027 its lowest fares will include only a small underseat bag, with overhead-locker space sold separately.

For airlines and online travel agencies (OTAs), the question is no longer whether to unbundle but how far, and how to present the fare so that travellers trust it. To answer it, we tested five ways of packaging the same short-haul fare with a simulated panel of Southeast Asian and Asia-Pacific travellers, then ran a nine-question follow-up survey on why they chose as they did.

Which way of packaging a short-haul fare do travellers prefer?

Transparent all-in fares win on every measure; charging for cabin bags at the gate loses on every measure.

The simulated panel scored five packages for the same short-haul trip on purchase intent, relevance, uniqueness, credibility and ease of use, each on a 1–5 scale.

Three findings stand out. First, clarity beats cheapness when travellers judge the offer itself: the all-in package led purchase intent by 0.28 points over the runner-up and was the only one rated highly credible. Second, the gate-fee package is not a near-miss; its credibility and ease-of-use scores are the lowest in the test. Third, travellers respect full-service packaging but do not prefer it to a low-cost fare that is simply honest about what it includes.

Before running the test, we set a condition for rejecting our hypothesis: if either the underseat-only or the gate-fee package led on purchase intent, transparent packaging would be judged the loser. Neither did.

If travellers prefer all-in fares, why do most still book the cheapest one?

At the point of purchase, the size of the price gap outweighs the preference for clarity.

When the same simulated panel was asked which fare they would actually book next after hearing about overhead-bag charges, most chose the ultra-cheap underseat-only fare and about a quarter chose transparent all-in. Almost no one chose the gate-fee option.

The driver is price, not a taste for surprise fees. Asked why someone would still pick the underseat-only fare, more than two-thirds pointed to the gap between it and the all-in or bag-included price; only about one in ten said they could genuinely travel with an underseat bag alone.

This is a wallet paradox rather than a contradiction. Travellers reward all-in packaging when they evaluate it, then default to the lowest headline when the premium looks too large. The implication for operators is to close the gap, not to abandon clarity.

How do surprise gate fees affect traveller trust?

Fear of an airport surprise is widespread, and disclosure at booking is the minimum travellers expect.

Three in four simulated respondents rated their worry about being charged for a cabin bag at the gate as high or very high, and around four in five would rather pay a clearly disclosed fee when booking than gamble on the gate. Their reasons for preferring all-in or bag-included fares were consistent: knowing the total cost upfront, avoiding the feeling of being nickel-and-dimed, and distrust of unclear bag rules. Six in ten said they normally travel with a cabin bag that needs overhead space.

So what: any fare design that earns revenue from confusion at the gate works against both the product-test scores and travellers’ stated trust threshold. If an underseat-only fare stays on sale, the overhead-bag add-on should be sold, and priced clearly, at booking.

How large a premium will travellers accept for an included cabin bag?

Tolerance for a premium is real but modest: most of the simulated panel clusters at about 10%, not at the 30–40% an all-in bundle typically costs.

The survey asked how much more than the cheapest underseat-only fare respondents would accept for a fare with an overhead cabin bag included. More than half chose the lowest band offered (up to about 10%) and about a fifth chose 15–25%. Only a handful accepted 30–40%, the premium described for the all-in package that won the product test.

Treat these bands as a directional screen for where to start testing, not as price points. They do, however, explain the wallet paradox: an all-in fare at a 30–40% premium wins the evaluation and then loses the booking.

What persuades travellers to choose an all-in fare?

Showing the full cost side by side is far more persuasive than labelling.

Asked what would most move them towards an all-in or bag-included fare, nearly three-quarters of the simulated panel chose a total-price comparison: the cheapest fare plus likely bag and seat fees, shown next to the all-in fare. A smaller price gap came a distant second. A clear “cabin bag included” badge on its own moved few respondents.

What should airlines and online travel agencies do next?

Make clarity the default, remove gate traps, and price the included bag within the range travellers will accept.

The simulated panel was clear about the default it wants: more than four in five said transparent all-in or bag-included fares should be what airlines and travel sites show first, and none chose gate or last-minute cabin-bag fees as an acceptable default. Five actions follow.

1. Default to all-in or bag-included fares in search and merchandising. Keep underseat-only fares on sale, with the overhead-bag add-on priced clearly at booking.
2. Retire gate and last-minute cabin-bag fees as a routine revenue line. They ranked last on every measure and as an industry default.
3. Test included-bag premiums in the ~10% and 15–25% bands before committing to 30–40% all-in bundles. Reserve full all-in bundles, with seat and check-in, for routes where live tests show higher tolerance.
4. Show the total trip cost before checkout. Put the cheapest fare plus expected bag and seat fees next to the all-in or bag-included fare.
5. Validate on priority routes. This panel was weighted towards Indonesia and towards infrequent flyers (see Methodology); confirm critical fare bands with live bookers before large pricing changes.

The natural next step is a price-elasticity test: an included cabin bag at about 10%, 15–25% and 30–40% above the underseat-only fare, each shown with and without a total-price comparison, on the same regional panel. You can run a comparable concept test on your own routes and fares.
