Biometrics and Digital Twins Are Changing the Rules of Global Air Travel
The 2026 summer holiday season will usher in significant changes at the world's largest airports. The familiar chaos of searching for boarding passes, passport checks, and tedious waits at the baggage carousel is gradually becoming a thing of the past. They are being replaced by intelligent systems that make passenger transit virtually seamless.
The main driver of this technological revolution is colossal losses. According to a recent report from the Society for Aeronautical Telecommunications International (SITA), with a record passenger traffic of 5 billion, airlines manage to lose or delay approximately 24 million bags per year.
This represents a financial nightmare for the industry: recovering just one lost suitcase costs a carrier an average of $260. With an average net profit of just $8 per passenger, one lost bag completely "eats up" the revenue an airline would otherwise receive from selling 30 seats on a flight. The implementation of high-tech solutions has become a matter of economic survival for aviators.
Biometric Corridor: Your Face Instead of a Passport
This summer's top trend is the concept of Tokenless Travel. International hubs, including Singapore's Changi Airport and several European airports, have begun implementing end-to-end biometrics en masse. According to SITA, biometric border control is already operational at 54% of airports worldwide, and this figure will increase to 83% by 2028.
The system works simply: when checking in for a flight, passengers take a single digital scan of their face. A camera then recognizes them at every stage—from baggage drop and pre-flight security to boarding. There's no longer any need to take out your passport, print out barcodes, or open apps on your smartphone. This reduces the time spent completing all airport formalities by approximately 40 percent.
A "Digital Twin" for Your Suitcase
The second major innovation aims to eliminate those 24 million baggage errors. Airlines have begun actively implementing permanent electronic baggage tags (EBTs) with embedded Bluetooth modules and next-generation RFID chips, as well as integrating the WorldTracer system with personal passenger trackers (such as Apple's Find My).
When you check in your bag, a virtual "digital twin" of your bag is created in the app. The owner can see in real time on a smartphone map where their bag is located: on the loading carousel, in the cargo hold, or on a connecting flight (international transfers account for 39% of all baggage losses).
Integration of tracking systems has already reduced the percentage of irretrievably lost baggage by 90%. Digitalization is making the airports of the future a reality, turning check-in and waiting time into a comfortable part of the vacation.
