At the European level, Fraud rates represent between 6% and 14% of activities, according to people who admit to having already committed fraud. Even more worryingly, between 51% and 75% of respondents believe that it is easy to defraud. In the aviation sector, this perception is reflected in the increase in documentary fraud. With the acceleration of ticket prices, the multiplication of digital services and the increase in customer expectations, fraudsters have found particularly favorable ground: the document. Today, a fake plane ticket, a modified bill or a falsified medical certificate may be enough to trigger reimbursement, compensation or loyalty credit by airlines. And in the majority of cases, these frauds remain extremely difficult to detect. To find out more, read the rest of this article.
Why is travel fraud exploding in 2026?
In 2026, the reality is simple. A few forged documents, whether it's a fake airline ticket, a modified bill, or an altered medical certificate, may be enough to get a refund, compensation, or benefits associated with airline loyalty programs.
Indeed, the documents are edited, the amounts are increased, the supporting documents are reused, medical care is invented. And nearly 90% of these scams fall under the radar of traditional human controls.
Several factors explain this increase in attempts at airline ticket fraud and travel agency fraud.
An increase in flight prices
For several years, the price of air tickets has risen sharply due to inflation, geopolitical tensions and rising fuel costs.
In 2026, the Closure of the Strait of Hormuz, caused by the war in the Middle East, is disrupting global oil and gas flows. In particular, it leads to a surge in the price of kerosene. Companies must increase their rates, reduce certain routes or apply fuel surcharges.
For travelers, each travel incident now represents a greater financial cost than before. A cancelled flight, extended delay, or lost luggage can quickly lead to high expenses.
In this context, some passengers are more interested in recovering money, sometimes by exaggerating a claim or by sending modified supporting documents in order to obtain greater refunds or compensations.
Air customer service: between speed and risk of fraud
Travelers today expect fast refunds, immediate compensation, and seamless customer journeys. However, passengers' rights are strengthening and compensation procedures are becoming more and more well known to the general public. Requests related to delays, cancellations or denied boarding now represent billions of euros for the aviation sector each year.
Airlines must therefore deal with a considerable volume of complaints in a very short time in order to maintain a good customer experience.
This operational pressure sometimes reduces the time spent on documentary checks. Result? The teams analyze thousands of supporting documents every day, often urgently, which creates an environment that is particularly favorable to document fraud and false credentials.
In this context, airline fraud teams are facing increasing operational pressure.
Flight refunds and cancellations: an ideal gateway for fraudsters
The first playground for fraudsters is travel refunds and cancellations.
In many cases, travelers send fake ticket invoices in order to get a refund, often higher, from insurance or customer service.
Other types of fraudsters use fake medical certificates to cancel a last-minute flight at no cost.
The fraud pattern is often the same:
- the change in the ticket amount
- The change of the passenger's name
- the alteration of the reservation date
- the creation of a false medical document or fake prescription
Then comes the reuse of the document already used elsewhere.
For airlines, the impact is considerable. Each request requires time-consuming human verification. Teams need to check documents from different countries, in different languages and in various formats.
The manipulations are often discreet but effective.
Lost baggage claims: a breeding ground for fraud
Declarations of lost or damaged baggage represent another major vulnerability point for airlines.
When a suitcase disappears, companies generally ask for proof of purchase in order to compensate for the items contained in the bag. This is where fraudsters come in.
Refund teams receive falsified invoices indicating, for example, the presence of:
- luxury jewelry
- high-end watches
- designer bags
- electronic equipment
In some cases, the amounts are simply increased. In others, the documents are entirely fabricated and the luggage has never contained such an object.
The problem is that these justifications often seem credible to the human eye. Official logos, consistent fonts, fake invoice numbers: fraudsters perfectly reproduce the visual codes of brands.
Compensation related to flight delays
Flight delays also lead to an increase in documentary fraud.
When a flight is cancelled or delayed, passengers can request reimbursement of ancillary expenses such as hotel nights, taxis or meals.
Again, supporting documents are frequently manipulated.
Fraudsters adjust expense amounts, reuse the same receipts multiple times, or create fake documents using templates available online. Some companies are even noticing organized networks capable of producing hundreds of perfectly structured false documents.
The danger is twofold:
- financial losses are increasing
- customer relations teams slow down the processing of all cases, including legitimate requests.
Ultimately, this climate worsens the overall passenger experience.
Travellers face longer processing times, reinforced checks and more complex journeys, which increases their dissatisfaction. This frustration can then fuel new fraudulent behavior, with some passengers seeking to recover financially the time lost or the inconveniences suffered.
Travel fraud: when loyalty programs become a new target
Loyalty programs are also becoming prime targets.
Les Miles represent a genuine parallel currency today. They allow you to get free flights, upgrades or exclusive benefits. Therefore, their financial value is very high.
How do fraudsters go about it? They use fake flight receipts, usurp loyalty accounts, resell miles, or create fake travel documents.
Airlines must then manage hybrid frauds combining cybercrime, identity theft and documentary falsification.
How can Finovox help airlines detect fake documents?
Finovox helps businesses detect documentary falsifications, regardless of the type of document or language used.
Its technology analyzes invoices, identity documents, medical certificates, travel receipts or even PDF documents and images.
The analysis is based on several complementary bricks.
Digital analysis
Finovox is a fake document verification software. It detects the invisible traces left when a document is modified through various forms of sub-analysis:
- metadata analysis
- software analysis
- visual analysis
- Learning documentary templates
Content analysis
In addition, Finovox also checks the consistency of information through:
- data extraction
- the intersection with internal and external bases
- detecting inconsistencies
- Control of amounts and dates
This approach makes it possible to detect anomalies that cannot be identified manually.
Why is the community essential against fraud?
In 2026, a fraudulent document detected by an airline can be reused with another player in the sector a few days later.
A false medical certificate or a modified document refused by a company can thus be sent to another airline, to a travel insurer or to a travel agency. The challenge is therefore becoming collective: the more actors in the aviation sector share fraud signals, the more difficult it becomes for fraudsters to reuse the same documents from one company to another.
The sharing of knowledge is becoming essential to act as an anti-fraud community logic.
This is precisely the approach developed by Finovox. When fraud is detected by an actor, it can be instantly recognized if it reappears elsewhere.
Fraud patterns are centralized, falsification models are shared, and detection capabilities are continuously improving thanks to collective intelligence.
In other words, the detection of one benefits everyone.
This collective intelligence makes it possible to anticipate new fraud methods before they become widespread.
