In the highly dynamic environment of civil aviation, inflight teams serve as the frontline in shaping passengers' perceptions of airline service quality. However, discrepancies often arise between passenger expectations and the actual experiences delivered, primarily due to misaligned or inconsistent communication practices. This study explores the critical role of strategic communication in bridging expectation gaps between cabin crew and passengers, thereby enhancing the overall inflight experience. Through a mixed-methods approach combining passenger feedback analysis, crew interviews, and service quality audits across multiple airlines, the research identifies key communication breakdowns and their impact on passenger satisfaction. Findings reveal that unclear service announcements, inconsistent interpersonal communication, and cultural misinterpretations are major contributors to expectation gaps. Moreover, reactive rather than proactive communication strategies by inflight teams tend to escalate service failures and passenger dissatisfaction. The study proposes a strategic communication framework tailored for inflight operations that emphasizes proactive engagement, emotional intelligence, situational awareness, and real-time information flow. The framework advocates for structured pre-flight briefings, personalized passenger interactions, and adaptive communication protocols to manage service variability and individual passenger needs. Implementation of this model was piloted with select crew cohorts, resulting in measurable improvements in Net Promoter Scores (NPS), complaint reduction, and reported crew confidence. By addressing communication not merely as an operational tool but as a strategic asset, airlines can enhance service delivery consistency and foster trust among diverse passenger demographics. This research underscores the importance of training inflight personnel in communication strategy, emphasizing clarity, empathy, and cross-cultural competence. It concludes that closing expectation gaps through strategic communication is not only vital to improving passenger experience but also essential to strengthening brand loyalty in an increasingly competitive global aviation market.
