SWISS Airlines allows one 8 kg carry-on (55 x 40 x 23 cm) and one personal item in most fares, plus one 23 kg checked bag in Classic and Flex fares. Light and the new Economy Basic fares include no free checked or carry-on bag. Fees start around USD 90 per extra bag.

Packing for a SWISS flight sounds simple until you realize your allowance depends on your fare, your route, and even the aircraft you’re flying. A skier heading to Zurich has different rights than a day-tripper on the new Economy Basic fare. Get it wrong, and you could face gate fees of USD 100 or more.

What is SWISS Airlines’ baggage allowance in 2026?

Your SWISS baggage allowance depends on three factors: your travel class, your fare type (Light, Classic, Flex, Business), and whether you’re flying a European or intercontinental route. Economy Classic and Flex fares include one 23 kg checked bag, while Light and Economy Basic fares include none.

Here’s how the standard checked allowance breaks down by route and class:

A few important exceptions apply. On intercontinental routes, the Premium Economy Light fare drops to 1 x 23 kg, and Business Light and Business Comfort fares include just 1 x 32 kg. Star Alliance Gold, Miles & More Senator, and HON Circle members usually get one extra checked bag free except on Light fares.

What are SWISS Airlines’ carry-on baggage rules?

SWISS allows Economy passengers one carry-on bag up to 8 kg (17.6 lbs) measuring 55 x 40 x 23 cm, plus one personal item up to 40 x 30 x 15 cm. Business and First passengers get two carry-on bags. The one big exception: the new Economy Basic fare includes only a personal item, no carry-on.

Carry-on allowance by class:

• Economy: 1 bag (max 8 kg) + 1 personal item
• Premium Economy: 1 bag (max 8 kg) + 1 personal item
• Business: 2 bags (max 8 kg each) + 1 personal item
• First: 2 bags (max 8 kg each) + 1 personal item

A foldable garment bag counts as your carry-on if it stays under 57 x 54 x 15 cm. SWISS is known for enforcing the 8 kg weight limit at the gate, especially on full flights so weigh your bag at home to avoid a surprise gate-check fee.

Edge case worth knowing: If you fly Economy from Italy or the USA, or board a small aircraft like the Embraer 190, cabin space limits may restrict you to one carry-on item total. Plan to check your roll-aboard on these routes.

Breaking news: What is the new SWISS Economy Basic fare?

Economy Basic is a new low-cost fare from the Lufthansa Group, rolled out across SWISS for travel starting May 19, 2026. It includes only one small personal item (max 40 x 30 x 15 cm) no free cabin suitcase and no checked bag. Additional hand or checked baggage can be added from EUR 15.

Announced on April 23, 2026, this fare puts SWISS on par with carriers like Air France and low-cost airlines such as easyJet and Ryanair. SWISS says the change reflects shifting passenger behavior, offering day-trippers a cheaper entry point. European consumer advocates have criticized the move, pushing for a legal right to a free carry-on alongside personal items.

What this means for you: If you travel with anything more than a laptop bag, price out the Basic fare against Classic before booking. Adding baggage à la carte can quickly erase the savings.

What are SWISS Airlines’ baggage weight limits?

SWISS caps standard checked bags at 23 kg (50 lbs) in Economy and Premium Economy, and 32 kg (70 lbs) in Business and First. Carry-on bags are limited to 8 kg (17.6 lbs). No single checked bag exceeding 32 kg is accepted for health and safety reasons it must ship as cargo instead.

If your bag lands between 24 kg and 32 kg on an Economy ticket, you’ll pay an overweight fee rather than being turned away. Anything heavier must be split into two bags or sent through SWISS WorldCargo.

What are SWISS Airlines’ baggage dimensions?

A standard checked bag on SWISS must not exceed 158 cm (62 in) in total dimensions that’s length plus width plus height combined. Carry-on bags must stay within 55 x 40 x 23 cm, and personal items within 40 x 30 x 15 cm. Bags between 158 cm and 292 cm are accepted as oversized for an extra fee.

Key dimension limits at a glance:

• Personal item: 40 x 30 x 15 cm
• Carry-on: 55 x 40 x 23 cm
• Garment bag: up to 57 x 54 x 15 cm
• Standard checked bag: max 158 cm (L + W + H)
• Oversized checked bag: 158–292 cm (fee applies)

Bags larger than 292 cm total won’t be accepted as standard baggage and must be arranged as special or cargo shipments.

How much are SWISS Airlines baggage fees?

SWISS charges baggage fees per leg, and prices vary by route. A standard additional checked bag (up to 23 kg, under 158 cm) costs CHF 180 / EUR 150 / USD 200 / CAD 200 on many routes, though a second Economy bag from the US to Switzerland is listed at USD 90. Booking online in advance can save 20–30%.

Here’s a breakdown of the main SWISS baggage fees:

Always book extra baggage through “Manage My Booking” before check-in. Airport rates are consistently the most expensive option.

How much is the SWISS oversized baggage fee?

An oversized bag on SWISS (larger than 158 cm but up to 292 cm, under 23 kg) costs roughly EUR 110 on European routes and USD 280–300 on intercontinental routes. Overweight bags between 24 kg and 32 kg cost about EUR 50–60 in Europe and USD 130–150 intercontinentally.

Cost stacking scenario: Here’s the trap most travelers miss. If your surfboard bag is both oversized (over 158 cm) and overweight (over 23 kg) on a long-haul flight, the fees stack. You could pay the oversize fee (~USD 300) plus the overweight fee (~USD 150) over USD 450 for a single bag, per leg. On a round trip, that doubles.
