How to pack for two weeks or more in one carry-on

Packing November 3, 2026

Carry-on size limits for major airlines, packing lists for hot, mild and cold trips, how to handle laundry on the road, and what experienced light packers say they stopped bringing.

You can travel for two weeks, or two months, with a single carry-on if you pack for about one week and wash clothes as you go. The bag size you can use depends on the airline: large US carriers such as American and Delta allow a carry-on of 22 x 14 x 9 inches plus a personal item, while low-cost European airlines such as Ryanair include only a small under-seat bag in the base fare. Choose your bag around the strictest airline on your itinerary, build a mix-and-match wardrobe in quick-drying fabrics, and leave the just-in-case items at home.

Start with the bag: airline limits vary

There is no universal carry-on size. Limits differ between airlines, between fare types on the same airline, and sometimes between aircraft on the same route. Check the operating airline for every flight, not just the one you booked with, because codeshare and partner legs often have different rules.

Airline	Under-seat item	Overhead carry-on	Notes
American Airlines	18 x 14 x 8 in (45 x 35 x 20 cm)	22 x 14 x 9 in (56 x 36 x 23 cm), including handles and wheels	On regional American Eagle flights, bags larger than the personal-item size are valeted at the gate
Delta	Purse, laptop bag or small backpack that fits under the seat	22 x 14 x 9 in (56 x 35 x 23 cm), max 45 linear inches	On Delta Connection flights with 50 seats or fewer, larger items are tagged and loaded in the hold
Ryanair	40 x 30 x 20 cm, included in all fares	55 x 40 x 20 cm, up to 10 kg, only with Priority and 2 Cabin Bags	Without Priority, your whole trip must fit in the small bag
easyJet	45 x 36 x 20 cm, up to 15 kg, included in all fares	56 x 45 x 25 cm, up to 15 kg, if booked or included in your fare	Bringing a large cabin bag to the gate without booking it costs 60 GBP

Which bag size to choose

Flying mostly on full-service airlines: a bag at or just under 22 x 14 x 9 inches (roughly 55 x 35 x 23 cm) plus a small personal item gives you the most room. A soft backpack of around 35 to 40 liters is a common choice; a 20 to 21 inch wheeled bag also works.
Flying low-cost carriers in Europe: either pay for the larger cabin bag on each flight, or pack the entire trip into a bag that fits the free under-seat limit (40 x 30 x 20 cm on Ryanair). That is roughly a 20 to 25 liter daypack and is realistic for warm-weather trips.
Measure the bag packed, not empty. A soft bag that bulges can exceed its listed dimensions once full. Sizers at the gate measure the bag as you present it.

Liquids

Most airports still limit carry-on liquids, gels, creams and pastes to containers of 3.4 ounces (100 ml) or less, all in one quart-size clear bag (Delta, citing TSA rules). Solid toiletries (shampoo bars, stick deodorant, solid sunscreen) free up space in that bag. For anything else, buy it at your destination.

The core method: pack for a week, wash for the rest

The length of the trip barely changes what goes in the bag. Two weeks and two months look nearly identical because you plan to do laundry every few days. What makes this work:

One color palette. Pick two or three neutral bottoms and tops that all go together. Five tops and three bottoms that mix freely give you many combinations.
Quick-drying fabrics. Merino wool, synthetic blends and thin technical fabrics dry overnight when rinsed in a sink. Heavy cotton (jeans, thick T-shirts, hoodies) can take days.
Wear the bulkiest items in transit. Your heaviest shoes, jacket and warmest layer go on your body, not in the bag.
Multi-use items. Shorts that work as swim trunks, a scarf that is also a blanket on the plane, a rain shell that doubles as a windbreaker.
Buy consumables there. Toothpaste, sunscreen and shampoo are sold almost everywhere.

Packing lists by climate

These are starting points for a trip of two weeks or longer with laundry every three to five days. Adjust for your own habits, and wear one of each clothing item on the travel day.

Item	Hot (tropics, summer Mediterranean)	Mild (spring or autumn in Europe, Japan)	Cold (winter city trip)
Tops	4 to 5 light, quick-dry	4 to 5, including 1 long-sleeve	3 to 4 base layers (merino works well)
Bottoms	1 pair lightweight trousers, 2 shorts or skirts	2 trousers, 1 skirt or shorts	2 warm trousers
Warm layer	1 thin long-sleeve for planes and air-conditioning	1 fleece or light sweater	1 fleece plus 1 insulated jacket (worn)
Outer layer	Packable rain shell	Packable rain shell with hood	Waterproof shell over the insulated jacket
Underwear and socks	4 to 5 sets	4 to 5 sets	4 sets, thicker socks
Shoes	Walking shoes (worn) plus light sandals	Walking shoes (worn) plus 1 light pair if needed	Waterproof walking shoes or boots (worn)
Extras	Swimwear, hat, sunglasses	Scarf	Hat, gloves, scarf, thermal leggings

Beyond clothes, most light packers carry a small toiletry bag, a compact first-aid and medication kit, a phone and charger, one universal plug adapter (ideally with several USB ports), a power bank (batteries must stay in the cabin, per American Airlines), copies of key documents, and a foldable daypack or tote for day trips and souvenirs.

Laundry on the road

Sink washing: rinse underwear, socks and a top in the evening with a little soap or shampoo, roll the wet items in a towel and press to remove most of the water, then hang overnight. Quick-dry fabrics are usually ready by morning.
Self-service laundromats: plan one full wash roughly every week or ten days. Booking accommodation with a washing machine around the midpoint of the trip makes this easy.
Drop-off or wash-and-fold services: widely available in tourist areas of Southeast Asia and in many European cities. You drop a bag in the morning and collect it later the same day or the next.
Hotel laundry: convenient but usually priced per item; useful for one or two pieces, not a full load.

What people who've done it say

These are individual experiences shared on public forums. They show patterns, but your own needs will differ.

Six weeks in Southeast Asia from one carry-on. In a 2024 Rick Steves forum thread about items people packed but never used, one traveler who spent six weeks in Southeast Asia living out of a carry-on said the unused items were mostly COVID tests, too many masks, hand sanitizer and an oversized medicine kit. They added that one fewer top would have been fine, that they still overpack underwear, and that they do sink laundry without carrying a clothesline (Rick Steves Travel Forum).
The gadgets that did not earn their space. In the same thread, a long-time forum member said they stopped carrying a clothesline and sink stopper because they rarely found a place to use them, and now pack a small dry bag to wash clothes in instead. Another listed an insulated water bottle (hard to refill with cold water) and laundry detergent sheets (hotel soap did the job) among items they did not use. The original poster decided to leave the umbrella at home in favor of a packable raincoat with a large hood (Rick Steves Travel Forum).
Shoes divide people. Several posters in that 2024 thread said they regularly bring a second pair of shoes that never gets worn, and one said fashionable shoes proved useless and had to be replaced with practical walking shoes bought on the trip. Others disagreed: one experienced traveler said they will never travel with only one pair, after a companion lost a full day of a trip shopping for replacements; another said a single well-fitting pair of walking shoes has been enough even for three-month trips (Rick Steves Travel Forum). If your feet are hard to fit, a second light pair is cheap insurance.
Medication is the exception to cutting back. One poster in the same thread had almost stopped carrying cold and stomach remedies because they never used them, packed them one last time for Sicily, and then needed them when both travelers fell ill. Having the original box also made it easier to buy more at a local pharmacy (Rick Steves Travel Forum).
Check every airline on the route. In an older Rick Steves forum thread (2013 to 2014) about two weeks in Italy with carry-on only, one traveler said their 21-inch bag met Delta's rules on the way out, but the first leg home was operated by a different airline whose size and weight limits it did not meet, so they had to rearrange items at the check-in counter. In the same thread, another traveler who managed 16 days with a 19-inch bag noted that cotton items took two to three days to dry fully, and a third preferred drop-off laundromats to sink washing (Rick Steves Travel Forum).
Bag sizers leave little room. In a March 2026 Tripadvisor Air Travel thread, a traveler worried that easyJet's under-seat sizer might be so close to the stated 45 x 36 x 20 cm limit that a full bag could get stuck. Experienced forum members replied that compliant bags fit and that people who get charged have usually overfilled a soft bag beyond the limit, and advised measuring the bag once packed (Tripadvisor Air Travel forum).

Common mistakes

Choosing the bag for the outbound flight only. Partner airlines, regional jets and budget carriers on later legs can have smaller limits.
Measuring the bag empty. A soft bag stuffed full can exceed its listed size and fail the gate sizer.
Packing for every possible scenario. Umbrellas, clotheslines, extra books and spare shoes are among the items experienced travelers most often report carrying and never using.
Cutting the wrong things. Basic medication and a small first-aid kit are worth their weight; you may not find your usual brand quickly when you need it.
Relying on cotton. Jeans and heavy cotton take a long time to dry, which breaks the wash-as-you-go system.
Filling the bag to the limit on day one. Leave some space, or carry a foldable tote, so souvenirs do not force you to check a bag on the way home.
Putting batteries in a bag that might be gate-checked. If your carry-on is taken at the gate, remove power banks and spare batteries first.

Bottom line

Pick a bag that fits the strictest airline on your route, pack about a week of mix-and-match, quick-drying clothes, and plan on washing something every few days. Keep medication and one good pair of walking shoes; drop the umbrella, the extra shoes and the just-in-case gadgets. Measure your bag fully packed and check each operating airline's current limits before you fly, since they vary and change.
