Airlines With the Best Carry-On Policies (2026)

Not all carry-on policies are created equal. Some airlines let you bring a 12 kg bag for free; others make you pay $75 to put a bag in the overhead bin. This guide ranks the world's major airlines by their carry-on generosity — covering weight limit, size, what is free on the base fare, and which airlines are best for frequent travelers.

How We Rank Carry-On Generosity

Each airline is scored on:

1. Size allowance — larger dimensions = better
2. Weight allowance — higher limit (or no limit) = better
3. Base fare inclusion — carry-on free on cheapest ticket = better
4. Enforcement — lighter-touch enforcement = more practical benefit
5. Overhead bin space — aircraft quality matters

Tier 1: Best Carry-On Policies in the World

Southwest Airlines (US)

• Size: 24×16×10 in (61×40.6×25.4 cm)
• Weight: No limit
• Free on base fare: Yes — every fare
• Bonus: Also includes 2 free checked bags on every fare

Southwest is the clear US winner. No basic economy restrictions, no weight limit, larger-than-average size, and two free checked bags to boot. The only airline in the US that never charges for carry-on or checked bags on any fare tier.

Air Tahiti Nui (French Polynesia)

• Size: 55×40×25 cm
• Weight: 12 kg economy
• Free on base fare: Yes

12 kg is among the highest carry-on weight limits of any scheduled carrier in the world. Air Tahiti Nui (TN) connects Paris and Los Angeles to Papeete and carries the generous weight limit that reflects its Polynesian-French full-service heritage. A hidden gem for weight-heavy packers.

Turkish Airlines

• Size: 55×40×23 cm
• Weight: 8 kg (economy), 16 kg (business)
• Free on base fare: Yes
• Bonus: Istanbul (IST) hub positioning means generous widebody longhaul lift

Turkish Airlines combines an 8 kg allowance with a large fleet of widebody aircraft (777, A350, A330, 787) with ample overhead bins. The business class 16 kg allowance is one of the highest published limits for business cabin bags.

Emirates

• Size: 55×38×20 cm
• Weight: 7 kg (economy), 7 kg (business — higher in some fare buckets)
• Free on base fare: Yes
• Bonus: A380 and 777 fleet — enormous overhead bin space in all cabins

Emirates' 7 kg limit is modest, but its aircraft fleet compensates. The A380 has exceptional overhead bin space. Dubai (DXB) connections are smooth. Emirates also offers generous checked bag allowances (typically 30 kg economy), reducing pressure on the carry-on.

Lufthansa / SWISS / Austrian

• Size: 55×40×23 cm
• Weight: 8 kg
• Free on base fare: Yes (except Light Economy fare which restricts to one personal item)
• Alliance: Star Alliance

The Lufthansa Group (including SWISS, Austrian, and Brussels Airlines) offers 8 kg carry-on across nearly all economy fares. Light Economy fares (the stripped base tier on some routes) restrict to an under-seat item, but standard Economy includes the full 8 kg.

Tier 2: Good Carry-On Policies

Singapore Airlines

• Size: 55×38×23 cm (economy), varies by cabin
• Weight: 7 kg economy
• Free on base fare: Yes
• Bonus: Modern widebody fleet (A380, A350, 777); excellent service

7 kg is slightly lower than ideal, but Singapore Airlines' consistent service quality, clean aircraft, and generally relaxed enforcement make the travel experience smooth. Business Suites class allows 16 kg.

Qatar Airways

• Size: 50×37×25 cm
• Weight: 7 kg economy
• Free on base fare: Yes
• Bonus: Doha (DOH) hub is a well-run transfer point

Qatar's size limit is slightly more compact than competitors (50 cm height) but is a full-service carrier with generous checked baggage and excellent in-flight experience. Business class (Qsuite) includes two carry-on bags.

easyJet

• Size: 56×45×25 cm
• Weight: No limit
• Free on base fare: Yes — full overhead bin on every fare
• Context: A budget carrier giving more than many full-service airlines

easyJet is the best-performing budget carrier on this metric. No weight limit and a large size allowance on every fare makes it more carry-on-friendly than American, Delta, or United on their base economy fares. The lack of a weight limit is particularly valuable.

Delta Air Lines (standard Economy)

• Size: 22×14×9 in (56×35.5×23 cm)
• Weight: No limit
• Free on base fare: Yes (standard Economy); No (Basic Economy)
• Context: No weight limit is a major US advantage

On standard economy fares, Delta includes a carry-on with no weight limit. The no-weight-limit policy is the key advantage over most international carriers. Basic Economy removes this benefit.

British Airways

• Size: 56×45×25 cm (handbag) + 45×36×20 cm (under seat)
• Weight: No limit
• Free on base fare: Varies by fare tier (Euro Traveller: 1 cabin bag + handbag; Hand Baggage Only: 1 under-seat item)
• Note: BA's published system is complex — the "Euro Traveller" fare includes overhead bag; "Hand Baggage Only" fares do not

BA's full-service model includes a generous two-piece allowance on standard fares. The complexity of BA's fare naming is a downside.

Tier 3: Average Policies

American Airlines (standard Economy)

• Size: 22×14×9 in (56×35.5×23 cm), no weight limit
• Free on base fare: No — Basic Economy trap

Standard economy includes carry-on, but the prevalence of Basic Economy fares in AA's pricing makes carry-on access unpredictable at booking.

United Airlines

• Same pattern as American — excellent standard economy policy undermined by Basic Economy restrictions.

Ryanair (with priority add-on)

• Size: 55×40×20 cm at 10 kg
• With add-on: Reasonable for a budget carrier
• Without add-on: 40×20×25 cm under-seat only

Ryanair is acceptable when you buy the priority package — a 10 kg cabin bag is reasonable. The base fare is nearly useless for anyone with a real bag.

Air India

• Size: 55×35×25 cm
• Weight: 8 kg
• Free on base fare: Yes

Improving under new ownership. Generous by South Asian carrier standards.

Tier 4: Restrictive Policies

Wizz Air

• Base fare: 40×30×20 cm under-seat bag — effectively a small daypack
• With Priority: 55×40×23 cm, 10 kg

Worse base fare free allowance than Ryanair. Priority upgrade is required to fly with anything meaningful.

Spirit Airlines

• Base fare: Under-seat item only — never overhead bin access
• Cost: $35–$100+ to add carry-on

The worst major US carrier for carry-on travelers. Nothing in the overhead without payment. Ever.

AirAsia (base Starter fare)

• Base fare: Under-seat personal item; no overhead bin access
• Weight when added: 7 kg, strictly enforced

Standard Asian LCC model — functional once add-ons are purchased, but base fare is very lean.

For Frequent Flyers: What to Prioritize

If you fly primarily US domestic: Choose Southwest for simplicity. If forced onto AA/DL/UA, achieve status fast enough to unlock carry-on benefits on Basic Economy.

If you fly primarily intra-Europe: easyJet or Iberia/Vueling bundle fares. Avoid Ryanair/Wizz base fares.

If you fly long-haul international: Turkish, Singapore, Emirates, and Qatar all include carry-on on base economy. The airline choice depends on routing rather than carry-on policy.

If you are a minimalist packer: Carry-on policy becomes largely irrelevant once you master packing into 7 kg. All full-service carriers globally include 7 kg; most are generous with enforcement.
