The personal item is where the carry-on game has actually moved in 2026. Every airline still publishes a 22 x 14 x 9 inch carry-on dimension, give or take an inch, but the personal item has fragmented into a wild range, from 11.8 x 7.9 x 3.9 inches (30 x 20 x 10 cm) on VietJet to 18.5 x 8.5 x 13.5 inches on Southwest. That gap matters more every year, because more travelers are flying personal-item-only to skip carry-on fees, and “personal item” can mean anything from a laptop bag to a small roller suitcase depending on which airline you booked.

This is the part most carry-on guides get wrong. They quote “one personal item that fits under the seat” and call it a day. That is fine if you fly the same airline every trip. If you book whatever was cheapest last Thursday, you need actual numbers, in inches and centimeters, with a per-airline source. That is what this page is.

The quick answer: The smallest published personal item size in 2026 is VietJet at 11.8 x 7.9 x 3.9 inches (30 x 20 x 10 cm), with AirAsia and Scoot next at 15.7 x 11.8 x 3.9 inches (40 x 30 x 10 cm). The European standard is 40 x 30 x 15 cm (15.7 x 11.8 x 5.9 inches), used by most Lufthansa Group and other legacy European carriers. The most generous published personal item is Volaris at 17.7 x 13.7 x 9.8 inches (about 2,376 cubic inches). Eighteen airlines, including Delta, Emirates, Qatar, Singapore, and Cathay Pacific, do not publish exact dimensions and use a “fits under the seat” rule instead.

If you want quick lookups for a specific airline, the Travel Vient carry-on size checker holds the same data with bag-fit checks against any size you enter. The full ranking, organized by tier, follows.

Update (May 2026): Spirit Airlines ceased all operations at 2:30 a.m. ET on May 2, 2026 and converted to a Chapter 7 liquidation, so it no longer sells tickets or flies. Its 18 x 14 x 8 inch personal item spec is kept below as a historical reference only. If you used to fly Spirit personal-item-only to dodge carry-on fees, the same strategy works on Frontier, Allegiant, and Breeze, which still publish generous free personal items.

How we verified this

Same methodology as our carry-on weight limits guide. Quick recap so you do not need to context-switch:

• Primary source only. Personal item dimensions come from each airline’s official baggage policy page. Each airline below links to the corresponding travelvient.com/tools/carry-on-size/ page where the source URL is recorded.
• No estimates. If an airline does not publish exact dimensions, we mark it as “no published dimensions” rather than guessing. Many of the airlines in this category use a softer under-seat rule, which we explain in that section below.
• Both inches and centimeters. Most international airlines publish in cm and US carriers publish in inches. Where airlines publish only one unit, we convert from the airline’s primary value rather than rounding twice. Where airlines publish both, we use both numbers.
• Last-verified date per airline. Every entry has a verification date attached. Personal item allowances changed at four airlines in the last 12 months (Aer Lingus loosened to 40 x 30 x 20 cm, Vueling reorganized fare classes, Hawaiian removed personal item dimensions, JetBlue tightened on Blue Basic), so we re-verify on a 30 to 60 day cycle.
• Volume calculation. When we sort airlines by “size,” we use the cubic-inch volume (length x width x depth) of the personal item, not just the longest dimension. A 17 x 13 x 8 bag (1,768 cubic inches) actually holds more than a 18 x 14 x 6 bag (1,512 cubic inches) even though the longer dimension is the same.

If a number on this page does not match what an airline currently publishes, email us at [email protected] and we will re-verify within 48 hours.

Smallest published personal items: under 1,100 cubic inches (11 airlines)

These are the airlines with the strictest published personal item allowances. The absolute smallest is VietJet at 30 x 20 x 10 cm (11.8 x 7.9 x 3.9 inches), a true handbag-or-laptop-bag spec. Most of the rest are Asian budget carriers with 40 x 30 x 10 cm sizers (AirAsia, Scoot), but Cebu Pacific, Air Arabia, flydubai, Condor, and Canada’s Air Transat round out the size scale. If you fly any of these, your “personal item” is closer to a laptop bag than a daypack.

Air Arabia

10 x 13 x 8 inches (25 x 33 x 20 cm). About 1,040 cubic inches. The smallest published primary dimension (10 inches) of any airline in our data set. Last verified 2026-04-22.

Air Transat

17 x 5 x 12 inches (43 x 13 x 31 cm). About 1,020 cubic inches. The 13 cm (5-inch) depth is unusually shallow, far thinner than the typical under-seat bag, so a packed daypack that clears most airlines can fail Air Transat’s gate. Verified against airtransat.com 2026-06-20.

AirAsia

15.7 x 11.8 x 3.9 inches (40 x 30 x 10 cm). About 723 cubic inches. The 3.9-inch depth is the catch; even slim daypacks struggle to fit under that limit. Last verified 2026-05-05.

Cebu Pacific

14 x 8 x 8 inches (35 x 20 x 20 cm). About 896 cubic inches. One of the tightest personal item limits anywhere (8 inches wide); Cebu’s official help centre states the under-seat item is 36 x 20 x 20 cm (14 x 8 x 8 in). Last verified 2026-06-20.

Condor

15.7 x 11.8 x 5.9 inches (40 x 30 x 15 cm). About 1,093 cubic inches. Condor uses the European 40 x 30 x 15 cm standard, identical to Lufthansa Group, which makes it the most generous personal item in this tier. Verified against condor.com 2026-05-23.

EVA Air

16 x 12 x 4 inches (40 x 30 x 10 cm). About 768 cubic inches. EVA’s personal item is essentially the AirAsia spec measured in inches first. Last verified 2026-04-22.

flydubai

13 x 9.8 x 7.9 inches (33 x 25 x 20 cm). About 1,006 cubic inches. flydubai’s official hand baggage page lists a small under-seat item at 33 x 25 x 20 cm, on top of the main cabin bag. Last verified 2026-06-20.

IndiGo

13.8 x 9.8 x 5.9 inches (35 x 25 x 15 cm). About 798 cubic inches. India’s largest carrier, with a personal item allowance smaller than most European legacy carriers despite a higher carry-on weight limit. Last verified 2026-05-07.

Qantas

15.7 x 13.8 x 3.9 inches (40 x 35 x 10 cm). About 845 cubic inches. The 3.9-inch depth is the same restrictive cap that AirAsia uses; Qantas borrowed the spec for its 7 kg domestic cabin baggage profile. Last verified 2026-05-07.

Scoot

15.7 x 11.8 x 3.9 inches (40 x 30 x 10 cm). About 723 cubic inches. Singapore Airlines’ budget subsidiary uses the AirAsia spec almost identically. Last verified 2026-05-07.

VietJet Air

11.8 x 7.9 x 3.9 inches (30 x 20 x 10 cm). About 364 cubic inches. The smallest published personal item of any airline in our data set, a strict handbag or laptop-bag spec that counts inside VietJet’s 7 kg combined cabin baggage cap, confirmed on VietJet’s official baggage page. Last verified 2026-06-20.

European standard: 40 x 30 x 15 cm (15.7 x 11.8 x 5.9 in) (13 airlines)

This is the closest thing to a global personal item standard. Thirteen airlines publish the exact 40 x 30 x 15 cm spec, mostly European legacy carriers and Star Alliance/SkyTeam members in Europe. About 1,093 cubic inches. A typical 13 to 14 inch laptop bag fits this; a small daypack fits this; a 25-liter ultralight backpack with a slim profile fits this.

Air France

15.7 x 11.8 x 5.9 inches (40 x 30 x 15 cm). 1,093 cubic inches. Last verified 2026-05-05.

Austrian Airlines

15.7 x 11.8 x 5.9 inches (40 x 30 x 15 cm). 1,093 cubic inches. IAG sibling alongside British Airways and Aer Lingus, but Iberia uses a more generous personal item than either. Last verified 2026-05-04.

KLM Royal Dutch Airlines

15.7 x 11.8 x 5.9 inches (40 x 30 x 15 cm). 1,093 cubic inches. Same allowance as Air France (joint parent). Last verified 2026-05-04.

Lufthansa

Mid-tier: 1,100 to 1,700 cubic inches (18 airlines)

This tier covers most of the airlines that fall between the strict European standard and the generous US allowance. A typical 17-inch laptop bag fits this; a 30 to 35-liter travel backpack fits this; a soft-sided “personal item roller” with a low profile fits this. This is the practical sweet spot for personal-item-only travel: enough room for 3 to 4 days of clothes plus a laptop and toiletries.

Aer Lingus

15.7 x 11.8 x 7.9 inches (40 x 30 x 20 cm). About 1,463 cubic inches. Aer Lingus increased its personal item from the older 33 x 25 x 20 cm spec to 40 x 30 x 20 cm in 2026, moving it from one of the tightest European allowances to a mid-pack size, in line with the free under-seat bags on Wizz Air and Transavia. Last verified 2026-05-26.

Copa Airlines

17 x 10 x 9 inches (43 x 25 x 22 cm). About 1,530 cubic inches. Same dimensional spec as United, which is not a coincidence; Copa is a Star Alliance partner. Last verified 2026-05-07.

Jet2

15.7 x 11.8 x 7.9 inches (40 x 30 x 20 cm). About 1,463 cubic inches. UK leisure carrier; the small under-seat bag is free on every booking, alongside the 10 kg cabin bag. Last verified 2026-06-19.

Norse Atlantic Airways

15.5 x 11.5 x 5.5 inches (40 x 30 x 15 cm). About 1,093 cubic inches by its 40 x 30 x 15 cm sizer. Long-haul leisure carrier with a tighter personal item profile than its generous 22 x 18 x 10 inch carry-on would suggest. Last verified 2026-05-07.

Ryanair

15.7 x 11.8 x 7.9 inches (40 x 30 x 20 cm). About 1,465 cubic inches. This is Ryanair’s free under-seat allowance, confirmed at 40 x 30 x 20 cm on the official Ryanair Help Centre bag policy. To bring a larger bag, you must pay for “Priority & 2 Cabin Bags.” Last verified 2026-06-20.

Generous: 1,700 to 2,000 cubic inches (11 airlines)

These airlines publish noticeably larger personal item allowances than the European standard. A 40-liter travel backpack fits this; a true small roller suitcase fits this; the kind of bag that on a Lufthansa flight would be your carry-on becomes your personal item here. The US ULCC tier (Frontier and the now-defunct Spirit) sits one level higher; this tier is mostly mid-tier US legacy and Latin American carriers plus a few European budget exceptions.

Avianca

17.7 x 13.7 x 7.9 inches (45 x 35 x 20 cm). About 1,916 cubic inches. The most generous Latin American legacy personal item, alongside LATAM. Last verified 2026-05-05.

Azul Linhas Aereas

17.7 x 13.8 x 7.9 inches (45 x 35 x 20 cm). About 1,930 cubic inches. Azul’s official carry-on and personal luggage page sets the under-seat item at 45 x 35 x 20 cm, in line with the larger Latin American carriers. Last verified 2026-05-07.

easyJet

17.7 x 14.1 x 7.9 inches (45 x 36 x 20 cm). About 1,971 cubic inches. The most generous personal item among European budget carriers, by a wide margin. easyJet positions this as the free underseat allowance, which is unusually generous compared to Ryanair or Wizz Air. Last verified 2026-05-05.

Eurowings

15.7 x 11.8 x 9.8 inches (40 x 30 x 25 cm). About 1,815 cubic inches. Same length and width as the European standard but much deeper (25 cm vs 15 cm). Last verified 2026-05-07.

Gol Linhas Aereas

16.9 x 12.6 x 8.7 inches (43 x 32 x 22 cm). About 1,853 cubic inches. Gol publishes a small under-seat item of 43 x 32 x 22 cm up to 10 kg, a generous spec for a Latin American domestic carrier. Last verified 2026-05-07.

ITA Airways

17.7 x 14.2 x 7.9 inches (45 x 36 x 20 cm). About 1,985 cubic inches. The successor to Alitalia, with a markedly more generous personal item than most European legacy carriers. Last verified 2026-05-07.

JetBlue

17 x 13 x 8 inches (43 x 33 x 20 cm). About 1,768 cubic inches. Free on Blue and above; Blue Basic restricts you to this personal item only. Last verified 2026-05-05.

LATAM Airlines

17.8 x 13.8 x 7.9 inches (45 x 35 x 20 cm). About 1,939 cubic inches. South America’s largest carrier; nearly identical to Avianca’s spec. Last verified 2026-05-04.

Virgin Australia

17.7 x 13 x 7.9 inches (45 x 33 x 20 cm). About 1,816 cubic inches. Notably more generous than Qantas (845 cubic inches), reflecting Virgin Australia’s positioning as a friendlier alternative on domestic routes. Last verified 2026-04-22.

Most generous: over 2,000 cubic inches (8 airlines)

Eight airlines publish personal item allowances that are essentially full-size carry-ons by European standards. This tier is dominated by US ULCCs that charge for overhead bin access, paired with a generous “free” personal item to make the fare look attractive. American Airlines and Saudia are the legacy outliers in this group.

Allegiant Air

18 x 14 x 8 inches (45 x 35 x 20 cm). About 2,016 cubic inches. Free on all Allegiant fares; the overhead carry-on costs $35 to $75 separately. Last verified 2026-05-25.

American Airlines

18 x 14 x 8 inches (45 x 35 x 20 cm). About 2,016 cubic inches. The most generous US legacy personal item, paired with a 22 x 14 x 9 carry-on, gives you essentially two full-size bags free of charge. Last verified 2026-05-04.

Frontier Airlines

14 x 18 x 8 inches (35 x 46 x 20 cm). About 2,016 cubic inches. Same volume as American Airlines, oriented differently. Free on all fares; carry-on costs $59 to $75. Last verified 2026-04-22.

Saudia

18 x 14 x 8 inches (45 x 35 x 20 cm). About 2,016 cubic inches. The only Middle Eastern legacy carrier in this generous tier; most of its peers (Emirates, Qatar, Etihad) do not publish personal item dimensions at all. Last verified 2026-06-09.

Southwest Airlines

18.5 x 8.5 x 13.5 inches (47 x 22 x 34 cm). About 2,123 cubic inches. This is the longstanding Southwest personal item sizer. Following its 2026 move to assigned seating, Southwest’s live help centre now describes the personal item only as “fits under the seat in front of you” without restating the numeric spec, so treat 18.5 x 8.5 x 13.5 inches as the working figure rather than a freshly republished number. Last verified 2026-06-20.

Spirit Airlines (ceased ops May 2026)

18 x 14 x 8 inches (46 x 35 x 20 cm). About 2,016 cubic inches. Spirit ceased all operations on May 2, 2026 (Chapter 7) and is no longer bookable, so this is a historical record. While it operated, the personal item was free on all fares and the carry-on cost $65 to $99; Spirit’s strategy was to publish a large personal item so the no-carry-on base fare still felt usable. Last verified 2026-04-22.

Viva Aerobus

18 x 14 x 8 inches (45 x 35 x 20 cm). About 2,016 cubic inches. Mexico’s other major budget carrier; same dimensional volume as Spirit and Frontier. Last verified 2026-05-07.

Volaris

17.7 x 13.7 x 9.8 inches (45 x 35 x 25 cm). About 2,376 cubic inches. The largest published personal item allowance of any airline in our data set. The 9.8-inch depth is unusual; most airlines cap personal item depth at 7 to 8 inches. Last verified 2026-05-05.

No published dimensions: under-seat rule (18 airlines)

Eighteen airlines do not publish exact personal item dimensions and instead use a “must fit completely under the seat in front of you” rule. In practice, the under-seat space on most modern aircraft fits a bag roughly 17 x 14 x 9 inches (43 x 36 x 23 cm), but the exact space varies by aircraft model and seat row (exit row, bulkhead, and window seats often have different under-seat configurations).

This group is heavily Asian and Middle Eastern legacy carriers, where the typical economy fare allows one carry-on plus one personal item but combines both into a single 7 kg total weight allowance. The airline polices weight rather than personal item dimensions.

How to choose a personal item bag that works on every airline you fly

If you fly only US legacy and ULCC carriers, almost any 18 x 14 x 8 bag will work. If you mix in any European legacy carrier (Lufthansa, Air France, KLM, etc.), you need a bag that fits 40 x 30 x 15 cm. If you fly Asian budget carriers (AirAsia, Scoot), you need a bag that fits 40 x 30 x 10 cm, which is a 4-inch-deep slim profile bag.

The honest answer: there is no single bag that fits all 75+ airlines on this list. The narrowest depth (3.9 inches on AirAsia, Scoot, Qantas) is genuinely tight. Most travelers solve this by either:

1. Pick the strictest airline you typically fly and buy to that spec. A 40 x 30 x 15 cm bag (European standard) is the sweet spot for most international travelers. It will not fit AirAsia or Scoot, but it works for everywhere else.
2. Pack the bag soft so it compresses. Soft daypacks and packable totes work better than rigid laptop bags because gate agents will let a slightly oversized soft bag pass if it visually fits the underseat space.
3. Use a smaller bag than you think you need. A 20 to 25-liter bag at 40 x 30 x 15 cm holds more than you think and avoids the “this is suspiciously oversized” problem.

For specific bag recommendations across ULCC strict-compliance and European legacy use cases, see our best personal item bags for budget airlines guide.

The bottom line

Personal item allowances span more than a 6x range in 2026, from 364 cubic inches on VietJet to 2,376 cubic inches on Volaris. The single biggest mistake travelers make is assuming “personal item” means the same thing on every airline. It does not.

If you fly mostly within the US, you have so much room that personal item dimensions barely matter. If you fly to Europe, optimize for 40 x 30 x 15 cm. If you fly anywhere in Asia or the Middle East, optimize for the under-seat rule and prioritize bag weight (most of those carriers cap combined cabin baggage at 7 kg total). And if you fly the strictest budget carriers (AirAsia, Scoot, Qantas domestic), optimize for the narrow 3.9-inch depth, which is a real constraint not all bags meet.

For everything else, the Travel Vient carry-on size checker does the lookup for you across every airline in this guide. If you want the data on your own travel blog or site, you can embed the carry-on size widget for free.

Sources and methodology

Every dimension in the table is hand-checked against the airline’s published baggage essentials page. A lastVerified date is recorded per airline; rows older than 60 days are re-checked before each guide refresh. Representative primary sources used for the major carriers include American Airlines, Delta Air Lines, United Airlines, Ryanair, easyJet, AirAsia, Emirates, and Singapore Airlines. Where an airline does not publish numeric personal item dimensions (18 of the 79, including Delta and Emirates), the table records “No published” rather than estimating.
