Airlines have been adopting yield management to optimise the perishable seat control problem and overbooking is a commoon strategy. This study outlines the connections between yield management, crises, and crisis communication. Using big data captured on a social media platform, this study aims to combine traditional yield management with emerging social big data analytics. As part of this, we use the twitter data on the 2017 United Airline (UA) to analyse the overbooking crisis. Our findings shed light on the importance of a more effective orchestration of yield management to avoid the escalation of crises during crisis communication phases. Highlights • UA had two image repair phases over the 24-hour apology tour. • The UA's insincere rhetorical apologies, and 'mortification' shown by their defensive posture was a main contributor to their crisis management failure. • Information on social media is propagated and spread rapidly and globally, which introduces new stakeholders into the conversation. • New stakeholders are difficult to define and target, thus making it hard to alter their perceptions and repair image.
