The Wall Street Journal broke the story that United CEO Scott Kirby called Delta's Ed Bastian to float a merger between the two carriers, and that the call came before United's rejected pitch to American. Mike and James dig into what was really going on there, whether a mega-carrier could help U.S. airlines compete against government-subsidized international rivals, and what happens to fares and secondary airports when competition shrinks. They also look at the Allegiant and Sun Country merger, the loss of Spirit, and why the three highest-volume airlines on the planet are all American.

Then the conversation heads to Europe, where wildfires in Spain and France are making headlines and low water on the Danube and Rhine is forcing river cruise lines to bus passengers between ports. James shares a genuinely useful piece of insider advice for anyone with a river cruise booked or planned: the size of the cruise line's fleet matters more than almost anything else when water levels drop, because only the larger operators can move you to a mirror-image ship downstream instead of canceling your trip outright.

The guys close out with the escalating airport lounge arms race, including crowded Centurion lounges and Southwest's new partnership with Chase to build co-branded lounges, plus the busiest day in commercial aviation history on July 23rd with more than 153,000 flights worldwide. Add in Edinburgh's new visitor tax and airfares up 25 to 50 percent year over year, and the takeaway is hard to miss. People are traveling anyway, because getting out into the world is something close to a human need.
