This priority boarding craze is getting out of hand. Almost no one wants to get on an airplane 45 minutes before it departs. People go nuts over boarding early because they have overhead bin anxiety. Can we just start charging for bin space? It's a precious resource for which demand outstrips supply.

Fun fact: What airlines refer to as costs is not an absolute measure of how much a carrier spends. A massive global airline like United can spend a lot more money from quarter to quarter and still keep its costs in check so long as it grows capacity during the quarter.

Is this finally it? Is the Boeing 737 Max returning to service? American Airlines is more confident than ever that the airplane will be ready by January 16, but that remains to be seen.

Delta’s planned $1.9 billion investment for a 20 percent stake in Latam is a pretty penny, but the U.S. airline is confident the deal will pay off by expanding its network in South America.

This is a bad development for frequent flyers. Many Uber and Lyft riders value their time, and they don't want to have to hop on a shuttle bus to get to a rideshare pickup area. Here's a better idea: Let people arrange for rideshare pickups at the terminals — but only if they pay extra money for the privilege.

Allegiant Air wants more customers to know what it is, so it's putting its name on a new NFL stadium. It's an out-of-character move for America's most frugal airline.

Aerolíneas Argentinas has focused heavily on improving its efficiency and customer service in a more competitive aviation industry, but its strategy could change depending on the outcome of Argentina’s upcoming national elections.

American Airlines has made a lot of excuses for its performance this year. It blames so many of its problems on a labor dispute and the grounding of the Boeing 737 Max. But perhaps there's something more here?

The majority of U.S. travelers don't have to worry about how they'll upgrade on United Airlines. But United's most loyal customers, who contribute more than their share of revenue, care deeply about the process. United can't make things too difficult for them, or they will defect.

It's hard to think of the bus as a disruptive form of mass transportation. But who knows? Maybe this company, Landline, will revolutionize how Americans buy airline tickets.
