Sometimes the clearest case for a technology comes not from scientists — but from the industry the technology is designed to serve.

In 2018, two years before COVID-19 and five years before any major government aircraft wastewater programme existed, the International Air Transport Association (IATA) published The Future of the Airline Industry 2035 [1]. The report — commissioned to identify how aviation would evolve over the following two decades — contained a statement that reads today as an uncanny prediction.

The 2018 IATA statement

Airports, the report said, are "strategic assets supporting governments' public health objectives for both detection and containment of diseases." The report went on to describe the aviation industry as taking increased responsibility for supporting "a global approach to managing infectious diseases."

This was 2018. COVID-19 had not yet emerged. SARS-CoV-2 did not exist. The CDC's TGS program had not been conceived. European Commission ad-hoc guidance for aircraft wastewater had not been written. The Lancet paper proposing a global aircraft surveillance network had not been published.

And yet IATA — the trade body that represents the interests of the world's airlines — was already describing airports as disease detection assets and the aviation industry as a stakeholder in global health management.

Why this matters

The IATA statement has three significant implications for anyone making the case for aircraft wastewater surveillance:

It resolves the "should airports be involved?" debate. The question of whether airports and airlines are appropriate partners for public health surveillance is sometimes posed as if it requires a policy innovation or a novel legal framework. The IATA 2018 report answers it differently: the aviation industry already conceptualized this role for itself seven years ago. The debate is not over whether airports should be part of health detection infrastructure — IATA already said yes.

It shifts the frame from request to expectation. When a public health authority approaches an airport operator about wastewater surveillance, the implicit framing can feel like an external obligation being imposed. The 2018 IATA report inverts this: airports that have not integrated biosecurity into their operations are behind the standard that their own industry body set in 2018.

It provides a business case in the airline industry's own language. The IATA report was not written for health ministries. It was written for airline executives and airport operators — people who think in terms of assets, operations, and regulatory positioning. Describing airport biosecurity in those terms, with reference to an IATA document, reaches a different audience than the public health literature does.

The COVID test

The COVID-19 pandemic was, in retrospect, the test of whether aviation had built the biosecurity infrastructure that its own industry body called for in 2018. The answer was largely no — the tools were not in place, the protocols were not standardized, and the wastewater surveillance systems were not running.

The result was well-documented: flight suspensions, border closures, travel restrictions, and economic disruption measured in hundreds of billions of dollars globally. The aviation industry that had predicted airports would be detection assets found itself, in the moment of crisis, without the detection capability.

The path from prediction to operationalization

Between the 2018 IATA prediction and the current moment, a significant infrastructure has been built. The CDC's TGS program, the European Commission's guidance, GLOWACON, and the UK–US bilateral programme collectively represent the early-stage operationalization of what IATA said was necessary.

For Thailand, the IATA framing is directly applicable to the Airports of Thailand authority, to the Civil Aviation Authority of Thailand, and to the Thai carriers that use Suvarnabhumi, Don Mueang, Phuket, and Chiang Mai. IATA's 2018 statement is their own industry's commitment — not an external public health demand. Building AWSS into Thai aviation infrastructure is, in that framing, delivery on a commitment made years before the pandemic proved why it mattered.

IATA told the aviation industry in 2018 what airports should be. The pandemic demonstrated the cost of not being it. The path from that gap to closure runs through systems like AWSS.
