Results and sensitivity analysis according to different traffic loads Net Promoter Score (NPS) is used to evaluate the customer loyalty. JetBlue sends out 35 surveys for each flight served. Our model establishes a quantitative link between good service and customer satisfaction to see how customer satisfaction can lead into actual rewards for JetBlue Airways Better service contributes to the actual rewards, but not as much as the intuition goes; heavier traffic load contribute to the actual rewards linearly Our investigation shows it is of central importance to assess the actual impact of word to mouth marketing given NPS.
