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.

>>As one carrier, United, backs off on basic economy, another, American Airlines, doubles down. Will this clear the field for American? Perhaps: United Backtracks on Basic Economy Fares as American Expands Them

>>Alaska’s decision to partner with Singapore Airlines, a Star Alliance member, may seem strange, but there are serious benefits for international travelers: Business of Loyalty: Alaska and Singapore Forge Codeshare and Loyalty Partnership

>>Airlines might have some trouble in the Caribbean longer term, but Florida should bounce back relatively quickly. That’s good news for American and other U.S. airlines: American Airlines Expects Irma Will Be Short-Term Blip on Revenues

>>Skift Global Forum is four years old, and now it’s a non-negotiable calendar appointment for serious travel companies: The Speakers at Skift Global Forum Are Just Amazing This Year
