These three bar charts expose a class satisfaction cliff: Business passengers are satisfied 69.5% of the time, while Eco Plus drops to 24.8% and Economy falls further to just 19.4%. The argument is simple and damning — 80.6% of Economy passengers are not satisfied. This is not a small gap; it represents a fundamentally different product experience for the airline's largest passenger segment. Side-by-side comparison makes this disparity impossible to ignore: the same airline, the same flight, and wildly different satisfaction outcomes depending on which section of the plane you sit in. Airlines appear to be optimizing for the minority who pay more, while leaving the majority of their passengers consistently disappointed.

Placing satisfied and dissatisfied service rankings side by side reveals a striking contradiction: Inflight Wifi Service ranks #1 among satisfied passengers (total score: 8,701) but is simultaneously the lowest-rated service among dissatisfied passengers (22,168 — the worst of all 14 categories). This means wifi is the most polarizing service in Economy — passengers either love it and it drives their overall satisfaction, or they rate it rock-bottom and it anchors their dissatisfaction. Online Boarding shows the same pattern, ranking #2 for the satisfied group and #3-worst for dissatisfied. These are not peripheral amenities — they are the pivot points. An airline that improves its digital touchpoints in Economy could convert its largest group of dissatisfied passengers at scale. By contrast, physical services like Baggage Handling and Inflight Service appear near the bottom of the dissatisfied rankings, suggesting passengers expect and accept lower physical standards in Economy — it is the digital experience they refuse to forgive.

Comparing the two pie charts reveals that age group distribution is remarkably stable between satisfied and dissatisfied Economy passengers — both groups are dominated by the 18–29 (≈29–30%), 30–44 (≈29–33%), and 45–60 (≈26–31%) cohorts. However, the most meaningful shift occurs at the extremes: the 60+ age group represents 14.2% of dissatisfied passengers but only 7.8% of satisfied ones — nearly double the proportion. This suggests that older Economy passengers are disproportionately likely to be dissatisfied, possibly because digital services (wifi, online boarding) — which we identified in Series 2 as the key satisfaction drivers — may be less accessible or intuitive for this demographic. Airlines designing Economy cabin improvements solely around younger travelers risk leaving their most consistently dissatisfied age segment behind. The middle-aged groups (30–44, 45–60) show the most balanced representation, suggesting they tolerate Economy conditions relatively better — or that they have lower baseline expectations.
