<h1>Airline's WhatsApp paperless boarding raises data privacy, security, consent, accessibility and truthful environmental claim risks</h1> A domestic budget airline has implemented WhatsApp-based paperless boarding at one regional airport and plans wider rollout, raising legal considerations including compliance with aviation security and boarding pass authentication standards, data protection and privacy obligations under applicable laws for transmitting passenger information via third-party messaging platforms, consumer protection issues around accessibility and consent for digital-only boarding, and environmental advertising claims accuracy under consumer and competition law. The carrier should ensure regulatory approvals, secure data handling agreements with messaging providers, clear passenger consent procedures, and verifiable metrics to support sustainability claims.
