John Bendoraitis, Executive Vice President and COO of Spirit Airlines, commented: “Our Guests don’t have to choose between a reliable airline and a great value when Spirit delivers both. As we prepare for the holiday season, travelers can count on us to get them to where they want to go, without paying top dollar to fly there. Thank you to our Spirit Team for their commitment to running a great operation and taking care of our Guests every day.”

However, financial strain remains an issue for the carrier. High fuel costs, leasing expenses, recent bankruptcies, and previous losses continue to impact the company’s balance sheet. These pressures could challenge the sustainability of current operational improvements if revenue does not increase or costs are not controlled.

The improved punctuality may offer some competitive advantage in the short term but larger competitors have greater capacity to absorb disruptions through bigger fleets. Any new cost overruns or fleet problems—such as increased engine issues—could make it difficult for Spirit to maintain its high level of punctuality.

Customer perception also continues to be an area requiring attention. While better on-time performance helps improve reputation, other factors such as cancellations, extra fees, customer service quality, and flight comfort remain important considerations for travelers.

Spirit's recent results represent a shift in perceptions about low-cost airlines’ reliability compared with legacy carriers. If sustained over time, this trend could alter consumer expectations regarding value-focused airlines versus traditional ones.

Delta Air Lines continues its focus on reliability as part of its strategy toward becoming a premium US airline—a move that keeps it near or at the top among national carriers for punctuality.
