Baggage


 * This article is about bags and other containers. See equipment and packing list for things carried within the baggage.

Baggage, also called luggage, are containers used to move all of a traveler's equipment around.

Usually you want to have a variety of options, which you can use as they suit your situation:
 * some big bag that can be packed away during transport (in the hold of planes and buses),
 * a carry-on bag that fits in overhead racks – big enough to hold everything for an overnight trip, or some essentials for a longer trip if the big bag gets lost, and
 * a little bag for items you use en route, such as a laptop or medications. Consider whether a vest or cargo pants can serve instead of a bag here.

When you're not flying, the number of items is less, and comfort when carrying them is more, important. In addition to your flight baggage, you might want to have bags to use when most of your luggage is at your hotel (or whatever your base). One of your carry-on bags can serve the purpose, or you may want to pack a bag specifically for this use.

As you choose any case or bag for travel, mind its empty weight, dimensions, ease to carry, and durability. Lighter cases allow you to pack more. But very large pieces (even lightweight) tempt packing too much; they may also violate weight or size limits. Soft, partially-full bags or sacks may fit in smaller or nearly-full bins where fixed-shape baggage can't. However, some delicate objects are better protected from the elements in hard shell bags.

Good luggage can be quite expensive, but it is often worth it since it can be re-used on multiple trips, and may be easier to handle or more reliable than cheaper models. Often good, if perhaps a bit battered, items are available in thrift stores. Some travellers deliberately use somewhat grubby luggage because it is less likely to attract thieves; this is especially important for high-value targets like a laptop or camera bag.

Items like a briefcase or backpack that will stop bullets are available. They are expensive and most travellers do not need them.

Types
There are many types of luggage:
 * A suitcase is used to carry large amounts of baggage; when packed, it might weigh.
 * A cabin suitcase or carry-on bag is designed with the maximum dimensions for cabin baggage aboard aircraft in mind.
 * A backpack can be differently designed, from heavy-duty hiking backpacks, to smaller fashion backpacks.
 * A briefcase is the archetypal accessory of business travel.
 * A cooler or cool box is used to carry perishable food around.

Combination items are fairly common. For example, you might get a soft bag that is an allowable size for carry-on, has wheels so it can easily be dragged around an airport, and also has straps so it can be carried as a backpack when necessary.

For some modes of transport, such as boating, canoeing or horse back riding, normal suitcases or big backpacks can be awkward or even impossible to use. If you are going to go on such journeys, check how to pack.

Suitcases
Suitcases are the normal luggage when you have organized transport. They are usually optimized for the restrictions on airlines (and those restrictions in turn are based on suitcases). They are less good if you actually have to carry them any significant distance, especially in places where you cannot use the wheels most of them have. Even big wheels require a smooth, hard surface, so if there are gravel roads or snow, hand-carrying can turn out to be necessary.

Suitcases generally come in these basic types: Wheeled bags are easier to carry. Two quality wheels should track well and last the life of the bag. Four-wheeled bags are easy to roll on smooth, hard surfaces such as airport hallways; however, they must be carried more often, and they tend to use an inch or so more length than two-wheelers. Bigger wheels help on less smooth surfaces, but also take some more space.
 * Hard-shelled cases, good for protection of fragile items. They are clamped and/or locked closed.
 * Hard-sided cases with zippers that can be padlocked for modest security. Some of these can be expanded.
 * Soft-sided or duffel bags.

Carry-on bags
The airline carry-on luggage size is particularly convenient for short trips, so sometimes bags of this size are called overnight bags or weekend bags. Many people keep one of these bags ready to grab in case of an unexpected trip. Generally, they're large enough to carry one or two full changes of clothes plus toiletries, a laptop computer, and other essentials. It may look like a small suitcase or be designed as a foldable hanging garment bag to carry a business suit (some airlines have different dimension rules for garment bags).

On an airplane, the maximum exterior dimensions for carry-on luggage varies by country, airline, and whether you are flying internationally or within a single country, but it is typically around 20x40x55 cm (about 8x16x22 in) for suitcases. Not all luggage has exactly the advertised dimensions, which means that the bag may not fit in the overhead compartment even though it is supposedly the correct size. If you fly to a wide variety of places, especially if you fly to smaller airports, then you may want to buy a bag that is one or even two sizes smaller than what you think you'll be entitled to.

If you're driving or taking a bus, train, or ferry, then carry-on bags have many advantages. The smaller size compared to larger suitcases means that they aren't very heavy, and are usually designed to be comfortable to carry. They are usually easy to stow in whatever space is available to you, including under the table at a restaurant while you're waiting for your connection.

Backpacks
Backpacks are easy to carry as they leave your hands free and distribute the weight better than suitcases (when you cannot or do not want to use the wheels), but few backpacks are optimized for airline restrictions. They are also not good at avoiding creases on your clothes. A fit man with a good heavy-duty backpack can carry about the typical airline weight allowance; a rule of thumb for trekking (with appropriate fitness level) is to carry at most one-fourth to one-third of your ideal weight.

Sizes vary from that of a big handbag to those suitable for a week-long trek in the wilderness. As the backpacks are soft (except for the frame), the space they take depends on how they are packed, but the capacity itself gives some overhead. Some are more flexible in that respect than others.

When you use a backpack for significant amounts of stuff, there are trade-offs regarding how easy it is to pack in available space (such as overhead racks on trains and buses) and how easy it is to carry. There are two main types: internal frame backpacks are more compact and usually the better choice for general use, while good external frame backpacks have some advantages on the trail. The shape of the backpack and the design of the strap system significantly affect how much you can carry, and how comfortably. Get a quality backpack from a specialist store, explaining your use case, and learn to adjust the straps. Also distributing weight right when packing is essential for balance and comfort.

Smaller backpacks often have no frame, which makes them lighter and easier to pack away, but less comfortable if heavy. They also lack the strapping to get the weight on the hips instead of the shoulders. Neither is a problem as long as the packing is light. Even with little to carry, pack so that you have no edges pointing into your back.

When carrying a backpack among people, you may have to take special measures against pickpockets. As the backpack is at your back, it is a fairly easy target; some backpacks for use in cold weather even have straps on the zipper pulls to allow easy opening with gloves on. Smaller backpacks can be worn on your front in high-risk areas. Consider getting a backpack with locking zippers, or run a large safety pin through each zipper. Generally, to deter a pickpocket, you don't need to have an impenetrable bag. You only need to avoid being the easiest and most tempting target in the crowd.

With a big or moderate backpack, do not forget your increased size. It is easy to cause a disaster in a porcelain shop, and to knock people over in the bus.

Accessories
Bags might have key locks or combination locks. Many others have zippers with holes that you can fit a padlock through.

It is fairly common to put a baggage strap around luggage, especially a large suitcase; usually the strap is passed through one of the case's handles so it cannot slip off. This reinforces the case making it stand abuse a bit better. It also makes your luggage easier to identify at baggage claim; there might be a dozen big grey suitcases but only one with a bright blue strap. Most straps include a lock; this will not stop a determined thief, but it might make a thief go for someone else's luggage.

Be careful—if you're flying in the United States and airport security decides to open your checked luggage for inspection, they will break your lock to do so if necessary and will not pay for any damage. Other countries have similar laws. Many suitcases now have a lock approved by the US TSA (Transportation Security Administration) which airport security can unlock without damaging it.

Some people put flags or other national symbols on their luggage, but depending where you are going this may be a seriously bad idea. If the airport in Back-of-beyond-istan is infested with thieves, then a suitcase with the flag of some rich country is a prime target for them.

Luggage storage
Luggage storage, also known as "left luggage" or "bag storage", is a service offered at many larger airports, train stations, and bus stations. For a fee, you can leave your bags in a locker or at a staffed counter and pick them up later. This is especially useful if you have a long layover in an interesting destination—leave your bags behind and explore the area unencumbered before getting them back and making your connection. Some of these services will allow you to leave your bags overnight. Note closing times – even when the lockers seem to be in a public space, that space may be locked in the night.

Hotels and hostels may also offer luggage storage, usually free, on the day you check in or check out, so you can enjoy the day unencumbered by luggage even when you can't leave it in your room. Not all luggage storage is (properly) guarded and not all hostels have a room or closet they can lock, so you should probably avoid leaving valuables.

Alternatives
You can often use a cardboard box instead of a suitcase, even on airlines. Boxes tend to be cheaper and lighter, but also more fragile (don't reuse for multiple journeys!) and a hassle to carry around. Make sure to use tape to seal the box tight and reinforce the corners and seams. Immigrants from the Philippines have a tradition of Balikbayan boxes, using them to send gifts to loved ones back home.

If you want to avoid having to bring everything with you, it's possible to have things mailed to a hotel for you before you arrive. Be sure to contact the hotel first to find out how you should address the package.

It is common to check in most luggage before boarding a flight and check it out at the destination airport. Although this option is more seldom used on trains, it is sometimes available, and might be available also with other modes of transport. Long-distance buses often allow you to stow luggage in a compartment under the bus when you're about to get on.
