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.

>>Low-fare airlines got there first. Now, big carriers are launching basic economy fares across the Atlantic. Expect some confusion as their customers figure out the rules: One Fallout From Long-Haul Battle on Airfares: No Free Checked Bag

>>Tag flights — when an airline lands in one international city and then almost immediately takes off for another — are disappearing from aviation as more airlines launch ultra-long-haul nonstops that make the stop unnecessary. But Qantas will probably keep its Los Angeles-New York nonstop for awhile: Why Qantas Flies a Nonstop Every Day Between New York and Los Angeles

>>It’s nice to see Alaska Air’s CEO saying all the right things about preventing sexual assault and harassment. Now let’s see if the new training and procedures actually work: Alaska Airlines CEO Outlines New Measures to Prevent Sexual Harassment

>>The conventional wisdom is that airline passengers will do anything to save a buck. That’s often true, but not always.

>>A new series of fares just launched by Air Canada should make it easier for discerning travelers to pick the fare that suits them best – as long as they’re willing to pay for it: Air Canada Launches New Economy Fares to Compete With Low-Cost Carriers
