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.

>>Security is all about tolerances. Yes, there’s probably a way to ensure that no airline employee ever steals an airplane again. But it’s probably not worth instituting such procedures. This was more likely a tragic fluke than anything: Don’t Expect Greater Airport Security After Alaska Air Crash

>>Last week’s stolen plane tragedy in Seattle made for great television. It also scared some travelers. But let’s call it what it was: a fluke: Let’s Not Get Carried Away With New Airport Security Procedures

>>Don’t look for airlines to impose weight limits on carry-on bags anytime soon, even though jet fuel prices are climbing and heavier loads eat up fuel: Customers Cram Carry-Ons as U.S. Airlines Look the Other Way

>>Southwest Airlines wants to keep its passengers happy, booking quickly, and coming back. In this video, Chief Revenue Officer Andrew Watterson explains some of the ways the airline achieves that goal: Video: Why Southwest Airlines Needs a Super-Fast Website
