The airline uses its account to communicate with almost 1.7 million followers, discussing concerns and providing feedback to flyers' tweets in English and Spanish. That news is not always welcome--such as no WiFi onboard JetBlue planes until later this year--but provides a layer of feedback in what can be a headache industry for consumer satisfaction. While JetBlue's team stays uniformly on point in its branding, the airline's social media team operates comfortably in the colloquial (if shallow) vocabulary of the social space.
