The landscape for low-cost carriers (LCCs) is undergoing a major transformation, as rising operating costs, shifting passenger preferences, and competitive pressures narrow the traditional cost gap between LCCs and network carriers.

This trend was the focus of discussions on the opening day of Routes Americas 2025, where airline and airport executives examined the future of LCCs in a changing market.

According to U.S. Department of Transportation (DOT) reports, the cost per available seat mile (CASM) for airlines has increased significantly post-pandemic, impacting LCCs’ ability to compete on ultra-low fares.

As inflation, labor costs, and evolving travel demands reshape the industry, LCCs face increasing pressure to differentiate themselves beyond pricing strategies.

Rising Costs & Shrinking LCC Advantage

Speaking at the event, John Pepper, Vice President of Corporate Development and Government Affairs at Allegiant, highlighted that LCCs have faced roughly a 20% increase in CASM, particularly due to higher labor costs. This has closed the gap between LCCs and traditional network carriers, making it harder for low-cost airlines to maintain their cost advantage.

“There’s been a close in the CASM gap between LCCs and other airlines,” Pepper said. “But the vast majority of customers still want to pay the lowest fare possible. What LCCs don’t have is the ability to subsidize costs the way network carriers do.”

This challenge is echoed in Federal Aviation Administration (FAA) findings, which indicate that fuel prices, regulatory compliance, and operational expenses continue to rise, further straining LCC profitability.

Changing Passenger Habits: Demand for Premium Services

While budget-conscious travelers remain a key market, there is a growing demand for premium services even within traditionally cost-sensitive passenger segments.

Nacim Yala, Chief Commercial and Strategy Officer at Dominican Republic-based LCC Arajet, pointed out that shifts in consumer behavior are visible across industries, where inflation has weakened low-end markets, while the middle-tier and premium segments continue to grow.

“All variable costs are much closer now. There has been a dislocation in demand, and the low end has suffered—businesses like Dollar Stores are shutting down, while the middle is doing quite well, driving demand for premium.”

However, data from the International Air Transport Association (IATA) suggests that while passengers appreciate enhanced experiences, affordability remains the primary decision factor for LCC customers.

Reimagining the Airport Experience

Beyond airfare pricing, passenger experience is becoming a crucial differentiator for airlines and airports.

Brett Smith, CEO of Propeller Airports, which develops U.S. passenger terminals, emphasized the need to treat every traveler as a first-class customer, providing concierge-style services, streamlined check-ins, and improved airport amenities.

“As a private company, we can implement changes faster than governments can. Making travel less painful benefits the entire industry, but does that mean passengers will pay more? I’ve yet to see data supporting that,” he said.

Frank Scremin, Vice President for Global Operational Services at Vantage Group, reinforced the importance of understanding different traveler expectations, whether they are business professionals on tight schedules or families seeking a relaxed experience.

Future Outlook: LCCs Adapting to Market Realities

As LCCs navigate rising costs and evolving customer expectations, the industry is expected to see new pricing models, hybrid service offerings, and infrastructure investments aimed at maintaining competitiveness.

The U.S. DOT and FAA continue to support airline expansion and cost efficiency initiatives, while airports worldwide are adopting smarter solutions to improve passenger flow, security, and overall travel experience.

As Routes Americas 2025 continues, industry leaders are focused on redefining the LCC business model, ensuring that low-cost air travel remains viable while adapting to the changing needs of modern travelers.
