Spirit Airlines

If you're an investor, it's not clear Spirit's model is the right one. But if you're a passenger, you should love the airline, even if you never fly it. Spirit is responsible for many of the U.S. fare wars we've seen in recent years.

The last time Spirit Airlines replaced its CEO, it bungled the public messaging. It's not letting that happen this time. Investors are getting more than one year of advance warning.

Louis XIII Cognac's most recent activation is a great example of how luxury brands are aligning with meaningful causes and influencers to appeal to luxury consumers' growing desire to feel their purchases are part of something bigger than themselves.

Spirit Airlines spent years angering customers with shoddy customer service. Now it wants those travelers to return, promising they'll find a kinder, gentler airline with an increased emphasis on on-time arrivals. But will they come back, or will they opt for deeply discounted fares from full-service airlines?

Spirit Airlines is hurting after a mixed quarter, and the outlook isn't good for the rest of 2017. The company's leadership, however, remains undeterred from its current strategy.

The union said it will comply with the order. But does that mean Spirit flights will immediately start running on-time again? Probably not.

It has not been a good week for Spirit's operation. But airlines often prevail in cases like these, so on-time performance could improve soon.

Focusing on reliability and customer satisfaction is the right move for Spirit, provided it can do it without increasing costs significantly. The airline's brand is not in strong shape, and it needs to be rehabilitated.

This is a curious move. In May, JetBlue will start flying smaller airplanes to Cuba, as demand is not as strong as expected. But now the airline wants to add more daily flights. Perhaps this is more of a long-term play.

It's hard to consistently make money in the airline industry. But Indigo Partners, led by former America West Airlines CEO Bill Franke, has an excellent track record. Once again, he is poised to make a big profit after buying an airline cheaply and taking it public.
