Throughout the week we post dozens of original stories, connecting the dots across the travel industry, and every weekend we sum it all up. This weekend roundup examines aviation.

For all of our weekend roundups, go here.

Ryanair is clearly doing some things right, but the sector has a structural problem that isn’t going to be solved by tweaking the edges.

Case Studies in Wellness Tourism That Go Beyond the Spa: New Skift Research: Wellness tourism is here for the long term. Understanding what it is today can help stakeholders find their place in this booming sector.
