Most packing trouble starts long before the zip is pulled. It starts with a bag that is too big, a list that was never written down, or a case that adds two kilograms before a single sock goes in. This guide, updated for the 2026/27 travel season, walks through the whole process in the order you actually do it: plan, choose the case, load it, protect what matters and check the rules that apply on the day you fly.
It works for a weekend city break and for a three-week trip with a checked bag. Use the sections you need and skip the rest.
Why efficient packing is worth the effort
Efficient packing is not about squeezing in more. It is about arriving with the right things, in good condition, without paying for excess weight and without hunting through the bag at every hotel. A well-packed case also makes airport queues easier: documents are at hand, liquids are ready for screening and nothing has to be repacked on the floor at the gate.
Three habits make the biggest difference: decide the contents from a written list, choose a case whose empty weight leaves room for your belongings, and group everything by category so that you can find it again in seconds.
Before you pack: the preparation checklist
Check the weather and the plan
Look at the forecast for each stop, then at your plan for the days: walking, beach, business meetings, a dinner that needs a jacket. Weather and activities decide the clothes. A raincoat on a stormy week and a light layer for cold evenings take less room than a second pair of shoes you will never wear.
Write the list of essentials
Start with the items that cannot be replaced on the road: passport or ID, tickets and booking confirmations, payment cards, medication, glasses and keys. Then add clothing, electronics and toiletries. Keep the list on your phone and tick items off as they go in the case. If you have ever left a charger behind, our article on the most frequently forgotten items when packing shows what other travellers miss most often.
Plan outfits, not piles
Plan outfits by day and keep to a small colour palette so that every top works with every bottom. Lay the planned outfits on the bed, then remove one item from each group. This simple step cuts the impulse to add "just in case" pieces that usually come home unworn.
Choosing the right suitcase
Size and type
Match the case to the trip. A compact cabin case is enough for a weekend, and it keeps you out of the baggage hall. For longer trips, or when you expect to bring things home, a larger case for the hold makes more sense. The aim is a case that holds everything without being forced shut, because an overfull bag is the quickest route to an extra fee. If you fly on a budget airline, read how to pack for low-cost airlines and avoid fees before you decide on the size.
Hard or soft
Soft bags flex into tight spaces and suit irregular items. Hard cases protect the contents from pressure and knocks, keep rain out and stack well in a car boot or a luggage rack. If you carry a camera, a drone, a laptop, medical instruments or anything else that would be expensive to replace, a hard case is the safer choice. Our comparison Hard or Soft Luggage: What to Choose goes through the trade-offs in more detail.
Which Peli Air case for which trip
The Peli Air series is made from Peli's HPX² polymer, which the product pages describe as up to 40% lighter than comparable hard cases. The models below are the ones most often used as travel cases. Sizes and capacities are taken from the product pages.
| Model | Best for | Key facts from the product page |
|---|---|---|
| Peli Air 1535 | Cabin trips with valuable gear | Carry-on size for most major airlines, IP67, retractable trolley handle, four interior options |

| Peli Air 1556 | Longer cabin trips with more room | 35 litres, wheeled, sized to maximum airline carry-on dimensions |
| Peli Air 1615 | Checked baggage with fragile contents | Rolling case, IP67 and MIL-SPEC, four interiors, five colours including French Blue |
| Peli Air 1637 | Photography and drone equipment in the hold | Deep wheeled case, three interior options, black or orange |
| Peli Air 1606 | Heavy kit and long trips | 50 litres, wheeled, black |
Airline cabin rules differ, so always compare the case dimensions with the limits of your carrier before you travel.
Cases to consider
-
Peli Air 1535 Carry-On Case: the cabin case for people who do not want to check their gear. -
Peli Air 1615 Checked Baggage: a rolling case built for the hold, with a pressure equalization valve and padlock protectors.
Organizing the inside of the case
Organizers, packing cubes and vacuum bags
Organizers split the inside of the case into zones, so a search for one item does not unpack everything else. Vacuum bags are useful for bulky knitwear and jackets, because pressing out the air reduces their volume. Use them for winter trips and for the return leg when the case is fuller.

Rolling or folding
Rolling saves space and tends to reduce creases in casual clothes such as T-shirts, jeans and knitwear. Folding is better for structured items such as blazers and dress trousers, which keep their shape when laid flat. Many travellers combine both: rolled items fill the gaps, folded items form the base layer.
Group by category
Divide the contents into clothing, toiletries, electronics and documents, and give each group its own cube or pouch. Keep all cables and adapters in one pouch and all toiletries in another. Unpacking becomes a matter of lifting out the cubes, and the chance of leaving something in a hotel drawer falls.
Packing the clothes
Versatile, lightweight pieces
Choose clothes that can be mixed and that work both day and evening. Lightweight fabrics take up less room and leave more of the weight allowance for the things you cannot replace. A sarong is a good example: it works as a beach cover-up, a scarf or a picnic blanket.
Underwear, socks and accessories
Small items are the best gap-fillers. Roll socks and underwear and tuck them into shoes, which keeps the shoes in shape and uses space that would otherwise be empty. Roll belts along the edge of the case or lay them flat at the base. Use zippered pouches for jewellery and small accessories so that nothing spreads through the case.
Heavy items at the bottom
Place the heaviest items, such as shoes, jeans and jackets, against the wheels end of a wheeled case so that it stays stable when upright. Fill the gaps with soft items and put delicate fabrics on top. Even weight distribution makes the case easier to roll and protects creasable garments.
Cosmetics and personal hygiene
Rules for liquids in cabin luggage
For cabin luggage, liquids are normally limited to containers of no more than 100 millilitres (3.4 ounces) each. All containers must fit in one transparent, resealable plastic bag of up to one litre, which is shown separately at security. Rules can change by airport, so check the current information from your airport before you travel. Our guides on how to pack cosmetics for a plane and transporting perfume on a plane cover the details.
Travel sizes
Choose sample sizes or refillable travel bottles. They save space, keep you inside the liquid limits and are enough for most trips. Solid alternatives, such as bars of soap or shampoo, remove the leak risk altogether.
Prevent leaks
Close all caps firmly, and tape them if the trip is long. Put shampoos, conditioners and lotions in separate bags or in a waterproof cosmetic case, and keep the case near the top or in a side pocket so that it is easy to take out at security. A sealed hard case with an O-ring, such as the Peli Air models above, also helps if the case is exposed to rain on the way to the aircraft.
Electronics and documents
Protect what you cannot replace
Carry passports, tickets, booking confirmations and medicines in the cabin bag, never in the checked bag. A waterproof travel wallet keeps papers dry and easy to reach. Laptops, cameras and other valuable electronics belong in padded compartments, or in a hard case with foam or dividers if the equipment is expensive to replace.
Cables, adapters and power banks
Pack chargers, a universal adapter and a power bank in a single labelled pouch. Power banks must travel in the cabin luggage and not in the hold, and most airlines publish limits on capacity. Read Power Bank in Carry-On Baggage – Rules and Limits before you pack one, and check the full list of what not to pack in your carry-on luggage.
Additional tips
Avoid overpacking
Write the list, lay everything out and take away one or two items from each group. Every garment and accessory should have a clear purpose. A lighter case is also easier to lift into the overhead bin and to carry up the stairs of a hotel without a lift.
Check the airline baggage rules
Every carrier has its own limits for size and weight, and the limits differ between cabin and hold. Check them on the airline site close to the departure date. If your airline is one of the big European carriers, the 2026 guides in our blog, for example the one on suitcases under 10 kg, collect the typical rules in one place.
If your suitcase is lost
Keep medication, a change of clothes and important documents in your cabin bag so that a delayed suitcase does not stop your trip. Label the case on the outside and put your contact details inside as well. Keep your boarding pass and the baggage tag. If the case does not arrive, report it at the airline desk before you leave the baggage hall and give a detailed description of the bag and its contents.
Frequently asked questions
How early should I start packing?
Start the list a week before departure and pack the case the day before. This leaves time to wash a missing item or buy a travel-size product and to weigh the case at home.
Is rolling better than folding?
Rolling usually saves space and works well for casual clothes. Folding is better for blazers and dress trousers. A mix of both gives the best result.
Which case is best for fragile equipment?
A hard case with a waterproof seal and a configurable interior gives the best protection. Models from the Peli Air series offer foam, padded dividers or a TrekPak divider system, depending on the model. Check the product page of the model you plan to buy for the available interiors.
Where should I keep documents and medicines?
Always in the cabin bag, in a pouch that is easy to reach. Never put them in the checked baggage.
Summary
Start with a written list and a plan for the days, then choose a case that suits the trip and the airline rules. Group the contents by category, put heavy items at the base, keep liquids and valuables where you can reach them and carry documents and medicines in the cabin. If you travel with equipment that is expensive to replace, a hard case from the Peli Air range is built for exactly that situation.
