Texts Between Sabre Execs About Farelogix Deal Fuel U.S. Antitrust Lawsuit: Sabre had tried the unorthodox legal tactic of pursuing its $360 million acquisition of Farelogix, an airline tech vendor, without waiting for approval from U.S. antitrust watchdogs. But it apparently didn’t count on federal attorneys claiming they have text messages between Sabre executives acknowledging the anti-competitive nature of the deal.

Why Do Airlines Suffer So Many Tech Glitches?: A British Airways hiccup earlier this month was merely the latest tech outage at a number of airlines. Why does the industry suffer from so many glitches? Experts point to some deeper reasons beyond the commonly heard “old tech” explanation.

Delta Sues Chatbot Vendor Faulted for Data Breach: Many grandmothers have tighter password security than tech vendor [24]7.ai allegedly did. A hacker had an easy time accessing the vendor’s code, and through it, the payment card data of up to 825,000 Delta customers. No wonder the airline is suing.

Airbnb Beat Expedia in Booked Room Nights: Does anyone remember when Travelocity was the leading U.S. online travel agency?

What it does clearly show is that the online travel pecking order is very much in flux.

High-Touch and High-Tech Find Common Ground With Travel Advisors: Virtuoso CEO: Virtuoso Travel Week drew record attendance to the annual event it likens to Fashion Week. While heavily touting the consortium’s new Wanderlist travel planning tool, it also emphasized the human touch.

TripAdvisor Drops Outmoded Little Wiser Owl Character From Ads: TripAdvisor’s new ad campaign is more hip than its usual fare. It also shows where its business is heading with hotel booking eventually having to share the limelight with tours and dining.

How Much the Human Connection Still Matters: Serving the emotional needs of clients, a key theme during this year’s Virtuoso Travel Week, is another indicator of how the travel advisor’s role continues to evolve beyond the booking of travel.

Travelport, IBM and BCD Travel Use Blockchain to Manage Hotel Commissions: Blockchain isn’t as hyped up as it used to be during the bitcoin craze, but companies are still finding its function as a secure ledger useful.
