After reaching a level of maturity, Breeze now needs to achieve sustained profitability

Over the course of five years, US carrier Breeze Airways has built up a fleet of roughly 60 Airbus A220s and developed a network of more than 300 year-round and seasonal routes to 95 destinations that are largely point-to-point. A majority of its routes don't have nonstop competition as the carrier avoids tangling with the country's largest carriers.

Breeze also touts its strong operational performance driven in large part by its simplified flying structure in which aircraft return to their respective bases on a nightly basis, creating a simplicity not accessible to other airlines.

But so far, consistent profitability is not included in those accomplishments. That's somewhat understandable given the current fuel environment. However, at some point Breeze will need to put the last piece of the puzzle in place - a financial performance that has the same reliability as its operational stability.
