In December 2018, IATA published an internal business case for end-to-end baggage tracking, recommending investment in three areas: RFID technology, modern baggage messaging standards (based on XML) and a platform to monitor compliance with Resolution 753. The objective was straightforward: deliver reliable, end-to-end baggage tracking across the industry in support of the baggage tracking requirements introduced under Resolution 753.
Eight years on, that business case is worth revisiting.
Historical Context
IATA's work to quantify the value of RFID in baggage handling predates the 2018 report by more than a decade. Early efforts to assess the benefits of moving from single-use barcode baggage tags to RFID-enabled alternatives began as early as 2005.
In 2016, IATA commissioned engineering consultancy ARUP to study the costs and benefits in detail as part of The Future of Air Travel: The Future Ready Airport initiative. That work led directly to the publication of the ‘End-to-End Baggage – IATA Business Case’ in December 2018. With more data points available, the financial and operational case for RFID was even stronger than earlier estimates had suggested.
The momentum continued the following year. At the 2019 IATA AGM, member airlines adopted a formal Resolution on Radio Frequency Identification in Baggage, which included an explicit environmental acknowledgement: the need to "investigate and pursue environmental techniques that minimize the waste produced using both traditional and RFID enabled baggage labels."
In less than a year after that 2019 AGM resolution, the airline industry was severely disrupted by the COVID-19 pandemic. Air traffic declined by 60% within six months of COVID's onset and did not fully recover until 2024.
The disruption went beyond lost traffic. Airline leadership has also changed considerably – only around 10-15% of the airline CEOs present at the 2019 IATA AGM remain in their positions today, with similar turnover across other senior roles. The current generation of executives has been focused first on COVID recovery and more recently on the disruption caused by the Middle East War. As a result, the drive that had been building toward RFID adoption pre-COVID has stalled – while the original problems, costs and benefits identified in the 2018 case remain largely unchanged.
This is precisely why the business case needs revisiting: not because the underlying case for RFID has weakened, but because the industry's attention, leadership and momentum moved elsewhere just as it was gathering pace.
What Has Changed Since 2018
Messaging
The most significant change since 2018 has been in baggage messaging. The XML standard proposed in the original business case is no longer a concept awaiting development; it is now operational through IATA's Baggage Information eXchange (BIX) service.
The discussion has therefore shifted from building a new XML messaging standard to encouraging airlines and airports to connect to infrastructure that already exists. The challenge is no longer technical development but industry adoption.
RFID
The case for RFID has strengthened over the past eight years. Airlines now have access to low-cost, single-use RFID tags incorporating an RFID inlay, alongside reusable Permanent Bag Tags (PBTs). Neither option had achieved significant industry adoption when the original business case was published.
Despite these advances, progress has been slower than anticipated. The disruption caused by COVID-19 interrupted many RFID programmes, while many of the airline sponsors responsible for early deployment have since moved into different roles.
Resolution 753
Resolution 753 came into force in June 2018. Eight years later, industry-wide adoption has exceeded 50%, with full compliance targeted for 2027. But depth and progress of implementation vary.
Industry surveys suggest 75% of airports now have the capability to support Resolution 753-compliant tracking, while as early as 2019, 80% of airlines have implementation plans in place. The focus has therefore shifted from committing to Resolution 753 to ensuring consistent implementation across airlines and airports.
Passenger expectations
One development absent from the 2018 business case has been the rise of passenger self-tracking. Consumer technologies such as Apple’s find my network and AirTag now allow passengers to monitor the location of their baggage independently of airline systems.
This has altered passenger expectations – baggage tracking is increasingly viewed as a standard service rather than a competitive differentiator. At the same time, it reinforces the importance of accurate airline tracking data, as passengers can now verify an airline’s baggage updates against the location information provided by their own tracking devices.
Tagging technology
The range of baggage tagging solutions has also expanded. Since 2018, Electronic Bag Tags (EBTs) and reusable PBTs have progressed from early trials to commercial airline deployments. Combined with low-cost single-use RFID-inlay baggage tags, airlines now have a broader choice of tagging solutions, ranging from disposable RFID tags to durable, reusable digital tags.
Industry Progress Since the Original Business Case
Airline deployment
Delta's RFID programme, launched in 2016, has expanded well beyond its own network. Delta's SkyTeam alliance partners — including Air France, KLM and China Eastern — have since adopted the same approach, extending RFID baggage tracking across one of the industry's major airline alliances.
Airport deployment
Airport adoption has followed a similar pattern of gradual expansion. Hong Kong International Airport (HKG) was an early adopter, implementing RFID baggage tracking in 2004, followed by Las Vegas (LAS) in 2006.
Since then, the most significant growth has occurred in China, where the Civil Aviation Administration of China (CAAC) has mandated RFID baggage tracking for all airports handling more than 10 million passengers annually, with implementation originally targeted for 2021. Although COVID temporarily derailed that timeline, Tier 1 Chinese airports are now equipped with the required RFID infrastructure. CAAC policy has since expanded further, requiring RFID infrastructure to extend across all domestic air routes and at small-to-medium-sized regional airports.
Operational performance
Operational experience has reinforced the case for RFID. Delta and other airlines have demonstrated baggage tag read rates exceeding 99%, while hands-free baggage tracking has reduced baggage delays and improved passenger experience. These operational improvements have also supported compliance with the baggage tracking requirements of Resolution 753.
BIX implementation
One of the most important developments since 2018 has been the introduction of IATA’s Baggage Information eXchange (BIX), replacing the legacy Type B messaging standard that underpinned baggage communications for decades.
By enabling modern XML and JSON based messaging between airlines, airports and ground handlers, BIX provides a more efficient platform for baggage data exchange. Its introduction reflects a recommendation adopted at the 2019 IATA AGM, calling on industry stakeholders to implement modern baggage messaging using IATA standards.
What Needs to Be Refreshed
RFID cost model
The 2018 business case based its financial analysis on a phased rollout across Tier 1 and Tier 2 airports between 2019 and 2027. Key assumptions included RFID printers costing approximately $1,500 per unit, readers priced at around $2,500 plus installation, system integration costs ranging from $30,000 to $150,000 per airport depending on size and operating costs of 3-6 cents per baggage tag. Together, these assumptions produced a projected three-year payback period. As an aside, some airports shifting to individual trays rather than conveyor belts in the baggage handling system therefore RFID readers are only needed next when the baggage is delivered to baggage make-up reducing the number of read points.
Each of these assumptions should now be revisited using 2026 cost data. This isn’t simply a matter of adjusting for inflation; the business case should also account for developments that were either unavailable or not commercially established in 2018. This includes low-cost single-use RFID inlays and reusable Permanent Bag Tags. Both have the potential to alter the balance between capital and operating expenditure while lowering the barriers to adoption for airlines and airports.
Messaging cost model
The original XML messaging model assumed the industry would need to build a new messaging standard from scratch, at a projected capital cost of approximately $678 million to construct and roll out the system. That investment would be offset by lower per-message costs and reduced manual handling.
That calculation no longer applies. With BIX now operational, the capital investment equired to build a new system assumed in 2018 is no longer required. Instead, the business case should focus on the cost of migrating airlines, airports and ground handlers to BIX, while decommissioning the legacy interfaces it replaces. Those migration costs can then be assessed against the ongoing benefits BIX delivers, including lower per-message costs, fewer message-driven mishandlings and reduced manual handling.
