The summer season came to a close and activity on social media slowed down.

Surprisingly, the majority of the activity wasn’t fueled by passengers expressing frustrations about flight delays on Twitter. Instead, Airlines gained more followers on two platforms, Instagram and Twitter.

Each Friday, we call out travel brands that have stronger than usual activity on social media. Using SkiftIQ, we’re able to track current performance versus past (60-day averages, unless otherwise noted) as well as notice spikes in activity that demonstrate a brand either has a viral hit on its hands, or a public relations mess to clean up.
