Hotel thefts, manipulation of unattended luggage and break-ins to accommodation are not problems confined to dangerous neighbourhoods or exotic destinations. They happen in luxury hotels, Airbnb apartments and popular European hostels alike. Many travellers place excessive trust in hotel safes – which have more weaknesses than most guests realise – or in TSA locks, which provide far less security than their name implies. The key to safe travel lies in combining several layers of protection, not relying on any single one.
Here are five practical approaches that actually work.
Trick 1: TSA Locks Are Not Enough – Add Your Own
Most modern suitcases have TSA locks. The concept was good in theory: allow security agencies to open bags without damaging them, while deterring casual theft. The practical problem is that the master keys that open any TSA lock have been publicly available online for years. For anyone with basic knowledge of airport and hotel security, a TSA lock presents no meaningful obstacle.
This does not mean you should avoid TSA-compatible suitcases. It means you should treat the built-in lock as one component of security rather than the whole system. When leaving your suitcase in a hotel room or transporting it on a bus, add external reinforcement.
A steel cable lock is one of the most effective additions. It allows you to thread the cable through the suitcase handle or telescoping arm and secure the bag to a fixed element in the room: a radiator, bed frame or furniture rail. A thief wanting to steal the whole bag would need to cut the cable, which takes time, creates noise and risks being caught. That combination is usually enough to make them look elsewhere.
An external compression strap with a combination lock protects both the zippers and the whole case against unwanted opening. It also prevents accidental zip opening during transport. The additional obstacle increases the time required for access, which is often enough to deter opportunistic theft.
Zipper blockers are small, inexpensive accessories that physically prevent a zip from being opened without first removing the blocker. Particularly effective in hostels where your bag may be unattended for many hours.
Peli Air Hard-Shell Cases – The Base Layer
A hard-shell suitcase adds a fundamental layer of protection that soft fabric bags cannot provide: structural rigidity that resists crushing and point pressure, and a surface that does not yield to improvised opening attempts. Peli Air cases with TSA-approved lock points provide the platform for all the additional security measures described here.
Trick 2: Create a Hidden Pocket Inside the Suitcase
A hotel thief works quickly. They search the obvious places first: external pockets, organiser compartments, visible pouches, cosmetics bags, the top layer of folded clothes. They rarely have the time or confidence to dismantle the suitcase lining or search inaccessible corners. This predictable behaviour can be used to your advantage.
In a hard-shell case there are usually spaces between layers of material or behind the lining. Some models have panels that can be slightly lifted to conceal flat items: banknotes, document copies, spare payment cards or small data drives. Externally, everything looks normal. Items hidden this way are significantly safer than those left loose under clothing.
An alternative is an internal lid organiser with a double-layer pocket behind a velcro or zip closure – invisible at first glance when the case is packed normally.
What to keep in a hidden pocket: an emergency payment card or small amount of cash; copies of your passport, visa or other important documents; a small drive with scanned copies of tickets and reservations; a PIN code recorded in an encrypted or disguised form.
Do not store everything valuable there – the hidden pocket is for an emergency reserve to use if your wallet or main bag is stolen. The most important items (passport, phone, primary card) should always be on your person.
If your suitcase has no ready-made compartments, a flat zip pouch taped or velcro-attached to the inside behind an internal divider is a simple, effective alternative. The goal is invisibility on first inspection.
Trick 3: Use a Cable Lock to Anchor the Suitcase
If the hotel safe is not trustworthy and you want to be sure the suitcase cannot simply be carried out of the room, a steel cable with an anchor lock is one of the most practical and affordable solutions. Even if a thief could access the interior, they may just take the whole bag – and this is what an anchor prevents.
A steel cable with a combination or key lock – the same type used for bicycles – works well. Thread it through the handle or telescoping arm of the suitcase and secure it to a fixed element in the room: a radiator, heavy bed frame leg or metal furniture structure. The cable does not need to be heavy – compact models fit in a bag side pocket and add negligible weight.
How to anchor correctly: thread the cable through the main handle or arm; attach to a fixed structural element (not a light piece of furniture that can be moved); secure with the combination or key lock; verify the suitcase cannot be moved or lifted without cutting or releasing the cable.
If there is no suitable fixed element in the room, the cable can be used inside a wardrobe, attached to the internal frame. This does not stop a determined thief with tools, but it introduces the delay, noise and effort that most opportunistic thieves avoid entirely.
This technique also applies to train compartments, bus luggage bays and airport waiting areas – anywhere the suitcase is briefly unattended. Solo travellers in particular benefit from cable anchoring in hostel dormitories where bags may be left for extended periods.
Peli RFID-Blocking Wallet – For Cards on the Move
Card skimming in hotel lobbies, busy markets and crowded transport is a separate but related security concern. An RFID-blocking wallet protects contactless cards from being read without your knowledge, which is relevant anywhere you carry cards in a crowd.
Trick 4: GPS or Bluetooth Tracker in the Suitcase
A small, discreet tracker does not physically protect the suitcase, but it enables location tracking anywhere in the world. This is increasingly standard practice not just for business travellers with expensive equipment but for ordinary tourists who want real-time knowledge of where their bag is.
The main options are Apple AirTag, Samsung SmartTag, Tile Pro and GPS trackers with SIM cards (like Invoxia). Bluetooth-based devices (AirTag, Tile) depend on passing devices in the network to relay location; GPS trackers with SIM cards send location independently but carry a monthly subscription cost. Both are adequate for most travel scenarios.
How to use: hide the tracker inside the suitcase – best placed in a shoe, under the lining or behind an organiser pocket. Track location through the associated app. In the event of theft, you have immediate information about where the bag is, specific evidence for police and the ability to act faster than waiting for a hotel investigation.
Where to hide it: inside a shoe stored in the suitcase (invisible, rarely accidentally discarded); behind the lining in a non-accessible pocket; in the lid organiser pocket covered by clothing; in a hidden compartment if the case has one.
A GPS tracker is a complement to physical security, not a replacement. It is most valuable when travelling to destinations with higher theft risk, or when carrying equipment whose value significantly exceeds the value of the suitcase itself.
AirTag/Tile considerations: they work by anonymously using nearby Apple or Tile devices to relay location. In most cities this works well; in very remote areas coverage may be limited. If you travel frequently to destinations with lower smartphone density, a SIM-based GPS tracker is more reliable despite the subscription cost.
Trick 5: Hidden Wallets, Pouches and Organisers on Your Person
The most secure place for your most important items is not the suitcase, the hotel safe or the in-room wardrobe. It is on your body. Documents, primary payment cards, cash, medication and access codes should be distributed across locations that minimise the consequences of any single theft or loss.
Types of hidden security worth considering:
Hidden document pouches worn under clothing, at the neck or belt, are ideal for a passport, emergency cash, a backup payment card and a hotel room key. Thin and close-fitting, they are invisible under a shirt or light jacket.
RFID-blocking wallets protect the data on contactless cards from electronic skimming. Useful in crowded environments: airports, city markets, hotel lobbies and public transport.
Travel organisers consolidate documents, tickets and reservations into one pouch, useful at check-ins, border crossings and when boarding.
Clothing with internal pockets (some travel jackets and hoodies have hidden internal compartments that are not visible from the outside) provide an additional layer.
The principle of distribution: do not keep everything in the same place. Divide cash between your main wallet, a hidden pouch and the concealed suitcase compartment. If one is lost or stolen, the others provide continuity. Carry only the day’s spending cash in your main wallet; keep the remainder secured in the hotel or distributed in hidden pouches.
What to always carry with you: a copy of your passport or ID; a small amount of local currency; an emergency payment card; a phone with bank contact numbers stored; passwords or access codes in a secure app. In destinations where losing access to documents and money is logistically complex, carrying a hidden backup of each is not paranoia but basic preparation.
The Hotel Safe: When to Trust It and When Not To
Hotel safes are a standard feature in most 3–5-star hotels and increasingly in apartments and hostels. But their presence does not guarantee security. Their primary function is to provide guests with a sense of security; the technical reality is more complicated.
Known weaknesses of hotel safes:
Default service codes. Many hotel safes have factory-set master codes (frequently 0000, 1234, 9999 or similar) that allow staff to open the safe if a guest forgets their PIN. These codes are often never changed after installation.
Master key or service code. Even with a changed personal PIN, the reception desk or maintenance team may have the ability to open the safe at any time. This is a legitimate operational need but creates an obvious vulnerability with dishonest staff.
Low build quality. Many hotel safes are low-grade devices that can be opened with basic tools in a few minutes without leaving obvious signs of tampering. Instructional content for doing this is widely available online.
Physical removal. Some safes are bolted to lightweight furniture rather than structural walls, meaning the whole unit can be removed.
How to use safes more safely: always set your own PIN, using a non-obvious sequence; verify the safe actually locks when closed (some cheaper models do not engage properly); if the safe seems mobile or damaged, do not use it for anything valuable; consider leaving a small “tamper indicator” inside (a folded piece of paper or small item that would be visibly disturbed if the safe was opened without your knowledge).
The safe is useful for: backup payment cards, part of your cash, reservation documents, passport copies – things you do not need daily but are not critical if accessed. Never store items essential to continuing your journey (original passport, medication, primary phone) in a hotel safe you are not confident in.
What Never to Leave in the Suitcase
Even a well-secured suitcase should not be treated as a safe for critical items. Certain categories of item should always travel with you, regardless of how many layers of security the bag has.
Documents and passport. Passport, ID card, driving licence, visas, boarding passes and health insurance cards should always be on your person. Losing them means a consulate visit, additional costs and significant logistical complications. Even in the safest destinations, keeping documents on your person rather than in accommodation is standard practice among experienced travellers.
Electronics. Laptops, tablets, cameras, drones and external drives are high-value, easily portable and easily resold. If you don’t need them in the room, don’t leave them there. Transport in carry-on baggage under your control.
Cash and jewellery. Do not store the bulk of your travel cash in the suitcase. A hotel thief looks for easily liquidated items: cash, jewellery, electronics. Keep only what you need for the day’s activities; store the remainder secured in layers as described above.
Medication. If you take essential medication, keep it with you at all times. A stolen or lost bag can leave you without access to prescription drugs in a country where obtaining a replacement involves significant bureaucratic and financial effort. The same applies to contact lenses, glasses and other medical equipment that is difficult to replace abroad.
The practical principle: the suitcase holds clothing and replaceable items. Everything irreplaceable – documents, medication, primary electronics – travels on your person or in a carry-on that never leaves your immediate control.
Summary: Security Is a System, Not a Single Lock
Effective luggage security in hotels and accommodation is built from layers, not from a single measure. A hotel safe that seems solid, a TSA lock and a hard-shell suitcase are individually insufficient. Combined with a cable anchor, a hidden internal pocket, a GPS tracker and the habit of keeping critical items on your person, they form a meaningful barrier.
The psychology of most opportunistic thieves is straightforward: they look for the easiest target. Every additional obstacle – a cable that requires cutting, a hidden pocket that requires searching, a tracker that enables rapid response – increases the time and risk required to steal your belongings, and correspondingly increases the probability that they will move on to an easier opportunity.
Security in travel starts with awareness of the risks and preparation before you arrive. Planning independently means thinking through accommodation security as part of the trip logistics, not as an afterthought on arrival. Distribute valuables, secure the bag physically, keep the essentials on your person, and do not rely on any single solution to do the whole job.
