It was an extraordinary reversal.

The founder who had created JetBlue's culture was no longer running the airline.

The company he had built had effectively told him that it needed a different leader.

For many executives, this would have been the moment to disappear.

Neeleman did something else.

He started again.

Part Three — Five Airlines and a Career Built on Starting Over

Being removed from the company he founded could have been the defining failure of David Neeleman's career.

Instead, it became another chapter.

Neeleman did not abandon aviation.

He went back to doing what he had always done best.

Build.

After leaving JetBlue's leadership, he turned his attention to Brazil.

In 2008, he founded Azul Linhas Aéreas Brasileiras, now known as Azul Brazilian Airlines. The carrier began operations in December 2008 and sought to connect Brazilian cities that were underserved by existing airlines.

Brazil presented a completely different aviation environment from the United States.

The country is enormous.

Its major cities are separated by vast distances.

Ground transportation can be slow and difficult between many regions.

For Neeleman, that created an opportunity.

Instead of copying JetBlue exactly, he adapted the low-cost model to local conditions.

Azul grew into one of Brazil's major airlines.

Once again, Neeleman had demonstrated that his ability was not tied to one specific company or market.

He understood how to identify gaps in an aviation system and create a business around them.

But Brazil would not be the end of the story.

In the United States, the airline industry was changing again.

The traditional low-cost model had evolved.

Consumers expected more digital services.

Mobile technology had become central to travel.

Airline networks were increasingly sophisticated.

And there was room for a new carrier designed from the beginning around modern technology and a different network strategy.

Neeleman saw another opening.

In 2018, he announced plans for a new airline that would eventually become Breeze Airways.

Breeze launched in 2021, during one of the most turbulent periods the airline industry had ever experienced. The COVID-19 pandemic had devastated global air travel, and airlines were confronting unprecedented uncertainty.

Launching an airline under those circumstances was almost unimaginable.

But Neeleman had never been particularly attracted to easy problems.

Breeze focused on connecting cities that often lacked nonstop service, using a fleet strategy built around efficient aircraft and a digital-first customer experience.

The airline's model reflected many of the lessons Neeleman had accumulated over decades.

Do not automatically copy the established industry.

Find the underserved customer.

Use technology to simplify the experience.

Keep the operation efficient.

And give people a reason to choose the airline beyond price alone.

By then, Neeleman's career had become something far larger than the JetBlue story.

He had been involved in the creation of Morris Air.

He had helped establish WestJet.

He had founded JetBlue.

He had founded Azul.

And he had launched Breeze.

Five airlines.

One career.

And an entrepreneur who had never completed college.

That final detail is worth returning to—not because dropping out of university is inherently admirable, but because Neeleman's story demonstrates how misleading a conventional definition of success can sometimes be.

His education did not happen primarily in lecture halls.

It happened inside businesses.

He learned by watching airlines operate.
