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.

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.

This analyst has a point. Perhaps Wall Street is undervaluing airlines because investors don't know the full value of airline frequent flyer programs. But it's not clear anything will change.

Someday Latin American economies will boom again, and the region's airlines will be big investor favorites. But until then, investors may remain wary of companies like Panama's Copa Airlines.

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.

Some sophisticated travelers like it when airlines embrace sophisticated personalization strategies, particularly when it means an airline will make a reasonably priced offer for something the customer values, such as an upgrade or a change to an earlier flight. But more casual travelers might find it intrusive. Regardless, personalization likely is here to stay.

Few airlines take marketing and public relations as seriously as Qantas. The airline should be commended for its efforts to persuade passengers they want to spend 17 hours on a plane, when they have other options.

It always seemed unlikely Aimia would accept this offer for the Aeroplan program. But this is bad news for Air Canada frequent flyers who have spent decades building their frequent flyer accounts. If nothing changes, they won't be able to use their miles as they expected in less than two years.

Norwegian is likely paying a lot more to a rent a gently-used Airbus A380 than it did for Wamos Air Boeing 747. But passengers hated the antiquated 747, and Norwegian took some criticism for flying it from New York to London. This is probably a better approach.

Travelers can leverage effective strategies to limit jet lag. There's only one problem. Most people lack the willpower to follow advice from the scientific community. That hasn't stopped Qantas, which hired a specialist to help.
