On-board Theft Increasing: What Should Hungarian Travelers Watch Out For on Summer Flights?

A new, often underestimated risk to passenger safety has come to the fore in the summer travel season: airlines and authorities are reporting an increasing number of on-board thefts, especially on long-haul, overnight, and Asia-connected flights. This phenomenon does not mean that flying has become dangerous, but it does mean that Hungarian travelers must be more conscious of how they handle cash, passports, bank cards, electronics, and medication kept in their carry-on luggage.

According to recent industry warnings, on-board thefts are not simply isolated inconveniences. Feedback from airlines received by the International Air Transport Association, or IATA, shows that over the past 12-18 months, more complaints have been received regarding missing money, phones, tablets, headphones, bank cards, and small valuables. Recent travel industry reports published on June 18, 2026, no longer describe this trend as just an Asian problem: affected routes increasingly include flights between Europe and Asia, major transit hubs, and crowded overnight flights.

This topic is important for Hungarian travelers because many distant destinations from Hungary can only be reached via transfer. Those starting from Budapest often begin their journey at Budapest Liszt Ferenc Airport, then fly further via Vienna, Amsterdam, Istanbul, Doha, Dubai, or other major hubs. Those traveling from Western Hungary or with a more flexible schedule often compare flights from Vienna Airport as well. A long route, a late evening departure, several hours of transfer and fatigue together can create a situation where the passenger pays less attention to their bag, while many valuables are placed in the overhead bins in the cabin.

Why Has the Problem Become More Visible Now?

On-board theft is not a new phenomenon, but the structure of the risk has changed. In the years following the pandemic, many passengers have become accustomed to traveling with carry-on luggage, partly due to more expensive checked baggage and partly due to shorter processing times. This means that more laptops, cameras, cash, passports, medication, and small electronic devices end up in the cabin. On crowded flights, personal bags often do not fit comfortably under the seat, so the passenger places them in the overhead bin. From then on, the bag seems close, but in reality, it is not under continuous control.

IATA's 2025 annual security report specifically addressed the fact that on-board thefts in several cases show an organized, cross-border pattern. According to airlines and security experts, perpetrators often monitor who puts their bag where, which passenger falls asleep, who travels alone, and when movement in the cabin decreases. Overnight sections, the turning off of lights, the quiet period after meals, and the use of the restrooms are all moments when a stranger reaching into the overhead bin is less noticeable.

Previous official data from Hong Kong authorities also showed that the number of thefts on airplanes increased again with the recovery of traffic after the pandemic. On flights to Hong Kong, 169 such cases were recorded in the first ten months of 2024, which was significantly higher than the same period of the previous year. The Singaporean police also issued practical warnings: cash and valuables should not be left in the overhead compartment, and any passenger suspiciously searching through another's bag should be reported to the staff immediately.

On Which Flights Should One Be Especially Careful?

It would not be responsible to say that a specific airline or a single route is dangerous. The problem is rather situational. Long-haul, overnight flights, completely full cabins, routes where many passengers travel only with carry-on luggage, as well as flights operating between major transit airports, deserve greater attention. From the perspective of Hungarian passengers, this could be, for example, a Southeast Asian trip via Amsterdam Schiphol, Istanbul, Dubai, Doha, or Singapore Changi.

The risk increases if the passenger arrives at the airport already tired before the long flight. After a late evening departure from Budapest, several hours of transfer and an intercontinental flight continuing at dawn, it is natural that one pays less attention. Therefore, it may be practical to plan so that critical transfers are not calculated with only the minimum connection time. If the route is very long, an airport lounge or accommodation can also reduce the rush; in such cases, reinforced pages such as hotels near Doha Hamad Airport, Dubai airport hotels, or Amsterdam airport hotels can be useful planning points.

What Should the Passenger Keep on Their Person, and What Should Not Go in the Upper Bin?

The most important rule is simple: whatever the journey cannot continue without should not be placed unattended in the overhead luggage compartment. Passports, ID cards, bank cards, cash, phones, keys, essential medication, glasses, insurance details, and documents required for entry should remain in a lockable inner pocket, waist bag, neck pouch, or a small personal bag under the seat. Clothing, toiletry bags, books, or items whose loss would be unpleasant but not make the trip impossible can go in the upper bin.

It is worth making a distinction between carry-on luggage and a personal survival kit. Carry-on luggage can be a cabin suitcase, which we place in the upper bin. The personal survival kit, however, is a smaller bag that remains close to the passenger throughout. This should contain documents, payment methods, phone, charger, medication, perhaps a thin sweater, and every tool that might be immediately needed during an unexpected transfer slip or baggage problem.

If the cabin crew asks to place the smaller bag in the upper bin as well, it is worth taking the valuables out of it first. This is not a lack of trust in the staff or other passengers, but basic travel discipline. The same applies if there is little space left during boarding and the bag must be placed several rows behind or ahead. The further the luggage is from one's own seat, the less it can be monitored.

How to Recognize Suspicious Situations?

One of the difficulties of on-board thefts is that the perpetrator's movements may seem ordinary at first glance. Everyone opens a luggage compartment, everyone looks for a sweater, headphones, or a charger. However, it may be more suspicious if someone searches in several different bins, does not reach for bags near their own seat, spends a long time fumbling through others' luggage, or pretends to have mixed up their luggage. In such cases, it is not the passenger's job to confront them. The best step is to quietly inform the flight attendant.

It is also important that the passenger does not delay reporting if something has disappeared. If it is discovered after landing that money or a bank card is missing, proving it is much harder. If the problem is noticed while still on board, the staff has a better chance of filing a report, requesting help from the destination authorities, and recording the circumstances. In the case of a missing bank card, immediate cancellation is at least as important as filing a complaint.

What Does This Mean in Terms of Insurance and Complaint Handling?

Many people only read the terms of travel insurance when trouble has already occurred. Yet, in the case of on-board thefts, it is especially important what document the insurer requests: a police report, airline certification, on-board incident report, invoice, or bank certification. Many insurances apply low limits to cash, and for electronic devices, exclusions regarding deductibles, depreciation, and unattended luggage are common.

Therefore, before long-haul trips, it is not enough to check if there is insurance. One must also check what it covers. If someone carries an expensive laptop, camera, or tool necessary for work, it is especially important not to keep it in the upper bin, unattended. For a business or remote worker's trip, data security also matters: there should be passwords, device tracking, cloud backups, and bank applications should not be easily accessible from a stolen phone.

Risk Continues During Transfer and After Arrival

The warning about on-board theft does not only apply to the flight itself. At the end of a long journey, the passenger is often tired, wants to leave the airport quickly, and pays less attention to their bag. This is especially true at large airports, where passport control, baggage claim, currency exchange, SIM card purchase, or transfer search follows after landing. Those who book or at least plan their airport onward travel in advance, rush less in the arrival hall. Useful starting points can be, for example, the overview of transfers from Istanbul Airport, Dubai airport transfers, Singapore airport transfers, or Hong Kong airport transfers.

The goal is not for the passenger to travel suspiciously, but that their most important items do not end up in a situation where they cannot see them for minutes or hours. The airplane cabin is a closed space, but not a private space. On a full long-haul flight, several hundred people move along the same narrow aisle, and the primary task of the staff is flight safety, not the continuous monitoring of every single luggage compartment.

Practical Checklist Before Departure

• Do not put your passport, bank card, cash, phone, and medication in the overhead bin.
• Create a separate small bag for under-seat storage, containing essential items.
• Do not keep easily accessible cash or valuable electronics in the cabin suitcase.
• On an overnight flight, check where your bag is and close the zippers before sleeping.
• If another passenger searches through several bags or behaves suspiciously, notify the staff.
• In case of a missing bank card, request immediate cancellation and keep proof of the reports.
• Before traveling, check what the insurance covers for on-board theft and what document is required for it.

The Bottom Line: Not Panic, but Better Travel Routines

The increase in on-board thefts is not a reason for anyone to cancel their summer or long-haul trips. Rather, it is a warning that safety during flying does not end at the security check and the boarding gate. Hungarian travelers should be especially conscious when choosing long Asian, Middle Eastern, or multi-transfer routes, because in these cases fatigue, crowding, and valuables carried in carry-on luggage together increase exposure.

The best defense is not complicated: keep important documents and valuables close to your person, put only less critical items in the upper bin, and do not leave suspicious movement unmentioned. Thus, the recent industry warning regarding on-board thefts can serve as a useful travel reminder rather than as fear-mongering news in the 2026 summer season.
