Abstract

This article examines the evolving competitive landscape within the global airline industry with particular focus on the structural transformations that have emerged following the COVID-19 pandemic. Through meticulous analysis of market concentration, pricing strategies, and emergent business models, this research identifies significant shifts in competitive dynamics that challenge traditional oligopolistic frameworks. Employing a mixed-methods approach incorporating quantitative market share analysis and qualitative assessment of strategic positioning, this study reveals the accelerated consolidation among legacy carriers juxtaposed against the disruptive growth of ultra-low-cost carriers in specific geographic markets. The findings suggest that while the industry continues to exhibit characteristics of imperfect competition, differential recovery trajectories have created asymmetric competitive environments across regional markets. This research contributes to the theoretical understanding of competition in network industries experiencing exogenous shocks and offers strategic insights for industry stakeholders navigating a fundamentally altered competitive landscape.

1. Introduction

The airline industry represents a quintessential case study in industrial economics, characterized by complex competitive dynamics that have evolved dramatically over recent decades (Borenstein & Rose, 2014). Since deregulation initiatives were implemented across major markets in the late 20th century, the sector has exhibited distinctive patterns of competition that challenge conventional economic models of market behavior. The strategic significance of hub networks, high fixed costs relative to marginal costs, and substantial barriers to entry have fostered oligopolistic market structures in numerous geographic segments (Brueckner et al., 2013).

The unprecedented disruption precipitated by the COVID-19 pandemic fundamentally altered these established competitive parameters, creating what Morrison and Winston (2021, p. 812) describe as “a natural experiment in market reconfiguration with few historical parallels.” Global air traffic declined by approximately 66% in 2020 compared to pre-pandemic levels, with differential impacts across carrier categories and geographic markets (IATA, 2023). This exogenous shock has catalyzed significant restructuring within the industry, including bankruptcy proceedings, state intervention through financial support mechanisms, and strategic repositioning among surviving entities (Abate et al., 2020).

As the industry progresses through its recovery trajectory, a comprehensive reassessment of competitive dynamics becomes imperative for both theoretical understanding and practical strategy formulation. This article contributes to this endeavor by examining emergent patterns of competition through a focused case study approach, analyzing market concentration metrics, pricing behaviors, and strategic adaptation across multiple carrier categories and geographic markets.

The central research questions addressed include: (1) How has market concentration evolved in the post-pandemic competitive landscape? (2) What novel competitive strategies have emerged among different carrier categories? (3) To what extent do traditional models of airline competition remain applicable in the contemporary environment? Through addressing these questions, this research extends existing literature on airline competition while providing actionable insights for industry stakeholders navigating a fundamentally transformed competitive environment.

2. Theoretical Framework and Literature Review

2.1 Models of Airline Competition

The theoretical understanding of airline competition has evolved substantially since the seminal work of Levine (1987), who established foundational concepts regarding contestability in airline markets. Subsequent scholarship has developed increasingly sophisticated models that account for the industry’s distinctive characteristics. Berry and Jia (2010) advanced a structural model of differentiated product competition that incorporated both business and leisure passenger segments, demonstrating how product differentiation strategies influence competitive outcomes. Their framework highlighted the significance of price discrimination practices and service quality differentiation as competitive levers.

More recent theoretical contributions have emphasized network economics as a critical determinant of competitive positioning. Brueckner and Proost (2019) developed a model demonstrating how hub-and-spoke network structures create asymmetric competitive advantages through economies of density and scope. This perspective has been complemented by Zhang and Czerny’s (2022) work on multi-market contact theory, which explains how carriers competing across multiple geographic markets develop tacit coordination mechanisms that modify competitive behavior.

As Gillen and Morrison (2023, p. 417) observe, “the competitive landscape in the airline industry represents a complex equilibrium between oligopolistic interdependence and localized competitive intensity.” This theoretical understanding provides the foundation for analyzing post-pandemic competitive dynamics.

2.2 Empirical Studies on Market Concentration

Empirical research has consistently documented the industry’s tendency toward concentration, particularly in specific geographic markets. Evans and Kessides (2019) conducted a longitudinal analysis of concentration ratios across major routes in North America, documenting a steady increase in four-firm concentration ratios (CR4) from 0.61 in 2000 to 0.78 in 2018. Similarly, Bilotkach and Hüschelrath (2020) analyzed European markets using Herfindahl-Hirschman Index (HHI) metrics, finding significant variation in concentration levels across different route categories but an overall trend toward increased concentration.

Recent research has begun to examine how the pandemic has influenced these established patterns. Preliminary analyses by Forsyth et al. (2021) indicate accelerated concentration in specific markets, with carriers possessing stronger pre-pandemic balance sheets expanding their relative market positions. However, comprehensive assessments of post-pandemic concentration dynamics remain limited, creating a significant research opportunity that this article addresses.

2.3 Strategic Adaptation in Crisis Contexts

The literature on strategic adaptation during industry crises provides valuable perspectives for understanding competitive responses to the pandemic. Wenzel et al. (2020) developed a taxonomy of strategic responses to severe industry disruption, categorizing adaptations along dimensions of retrenchment, perseverance, innovation, and exit. Their framework suggests that heterogeneous strategic responses create opportunities for competitive repositioning during recovery phases.

In the specific context of the airline industry, historical research on responses to previous disruptions offers relevant insights. Franke and John (2021) analyzed strategic adaptations following the 2001 terrorist attacks and 2008 financial crisis, identifying distinct patterns among network carriers, low-cost carriers, and regional operators. Their research suggests that disruptive events often accelerate pre-existing competitive trends rather than creating entirely novel competitive dynamics.

3. Methodology

This research employs a mixed-methods approach combining quantitative analysis of market concentration metrics with qualitative assessment of competitive strategies. The study utilizes a case study methodology focused on three geographic markets selected for their distinctive competitive characteristics and differential pandemic impacts: the North American transcontinental market, the intra-European short-haul market, and the Asia-Pacific international market.

3.1 Data Collection

Market share data was obtained from the Official Airline Guide (OAG) database, covering the period from January 2019 through December 2024. This dataset provides comprehensive information on scheduled capacity (available seat kilometers) by carrier across all routes within the selected markets. Supplementary data on yields and pricing strategies was sourced from the IATA Economics database, while financial performance metrics were collected from carrier annual reports and public financial disclosures.

Qualitative data on strategic positioning was gathered through systematic analysis of corporate communications, including investor presentations, annual reports, and public statements by executive leadership. This dataset encompasses materials from 34 carriers representing diverse business models and geographic positions, enabling comprehensive assessment of strategic adaptation patterns.

3.2 Analytical Approach

Market concentration was analyzed using both four-firm concentration ratios (CR4) and Herfindahl-Hirschman Index (HHI) calculations, enabling comparison with pre-pandemic benchmarks established in previous research. Changes in concentration metrics were assessed using time-series analysis with quarterly intervals to identify trend patterns and potential inflection points.

Strategic positioning was evaluated through thematic analysis of qualitative materials, employing a coding framework developed from the strategic adaptation literature. This analysis focused on identifying patterns in network optimization, pricing strategies, product differentiation approaches, and alliance/partnership configurations. The combined analytical approach enables triangulation between quantitative market structure metrics and qualitative strategic positioning data.

4. Findings and Analysis

4.1 Evolving Market Concentration

The analysis reveals significant shifts in market concentration across the three case study regions, with distinctive patterns emerging in each geographic context. In the North American transcontinental market, the CR4 increased from 0.73 in Q4 2019 to 0.89 in Q4 2024, reflecting substantial consolidation among major network carriers. This concentration increase was primarily driven by the permanent capacity reduction of several mid-tier carriers and the strategic retrenchment of smaller operators from competitive transcontinental routes.

By contrast, the intra-European short-haul market exhibited a more complex pattern. While the overall CR4 remained relatively stable (0.52 in Q4 2019 versus 0.55 in Q4 2024), significant recomposition occurred within the dominant carrier set. As Zhang (2023, p. 209) notes, “the relative stability in aggregate concentration metrics obscures substantial realignment among market participants.” Ultra-low-cost carriers significantly expanded their collective market share, while several traditional flag carriers experienced proportional declines despite receiving substantial government support during the pandemic period.

The Asia-Pacific international market demonstrated the most pronounced concentration increase, with the CR4 rising from 0.48 in Q4 2019 to 0.67 in Q4 2024. This dramatic shift reflects both the differential regulatory approaches to market access during recovery phases and the strategic advantages accruing to carriers with stronger balance sheets and government affiliations. The competitive landscape in this region has fundamentally reconfigured, with several previously significant carriers permanently reducing their international operations.

4.2 Pricing Strategies and Revenue Management

Analysis of pricing dynamics reveals divergent approaches across carrier categories that have significant implications for competitive intensity. Legacy network carriers have increasingly adopted sophisticated dynamic pricing models that Pearson and Fletcher (2022, p. 145) characterize as “microsegmentation and personalized revenue management.” These approaches leverage advanced analytics to implement granular price discrimination strategies that target specific customer segments with customized pricing structures.

Conversely, ultra-low-cost carriers have doubled down on transparent base fare models with unbundled ancillary services. This strategy has proven particularly effective in capturing price-sensitive leisure segments that have recovered more rapidly than business travel. The bifurcation in pricing approaches has intensified product differentiation within the industry while creating distinct competitive dynamics within different customer segments.

An emergent phenomenon identified in this research is what might be termed “strategic price leadership,” wherein dominant carriers in specific markets establish pricing patterns that are systematically matched by competitors. This behavior, observed particularly in markets with higher concentration ratios, suggests the development of tacit coordination mechanisms that moderate price competition despite the absence of explicit collusion.

4.3 Network Reconfiguration and Market Entry Patterns

The pandemic precipitated substantial network reconfiguration across all carrier categories, creating novel competitive dynamics in specific geographic markets. Legacy carriers have systematically pruned marginally profitable routes while concentrating capacity on core hub connections, effectively strengthening their dominance in specific fortress hub markets. This strategic retrenchment has paradoxically created entry opportunities for smaller carriers in previously contested markets where capacity has been permanently reduced.

The data reveals significant new market entry activity by ultra-low-cost carriers, particularly in leisure-oriented markets that have experienced stronger recovery trajectories. As Davidson and Ryerson (2021, p. 312) observe, “the pandemic has accelerated the bifurcation between business and leisure markets, creating distinct competitive environments with different entry barriers and profit potential.” This differentiation has enabled specialized carriers to identify and exploit specific market opportunities despite overall industry challenges.

A particularly noteworthy finding concerns the reconfiguration of international network strategies. Traditional network carriers have substantially reduced their point-to-point international offerings, instead concentrating capacity on core alliance routes that leverage partnership synergies. This strategic shift has significant implications for competition in international markets, potentially reducing effective competitive options for consumers despite nominal maintenance of service.

5. Discussion

5.1 Theoretical Implications

The findings of this research have several important implications for theoretical models of airline competition. First, they challenge simplified models of oligopolistic competition by highlighting the increasing segmentation of competitive dynamics across different market categories. The data suggests that the industry is evolving toward what might be termed “stratified competition,” wherein different market segments exhibit fundamentally different competitive characteristics despite existing within the same broad industry.

Second, the research extends network economics theory by demonstrating how exogenous shocks can reconfigure the competitive advantages derived from network structures. The strengthened position of carriers with dominant hubs in specific markets confirms Brueckner and Proost’s (2019) theoretical predictions regarding network resilience, while also revealing how network advantages can be amplified during recovery phases through strategic capacity allocation.

Third, the findings contribute to literature on competitive dynamics during industry crises by documenting heterogeneous recovery trajectories and their implications for market structure. The research supports Wenzel et al.’s (2020) framework of strategic response diversity while extending it to account for the influence of external interventions such as government support programs on competitive outcomes.

5.2 Practical Implications

For industry practitioners, this research offers several actionable insights. Carriers operating in markets experiencing increased concentration should anticipate evolving regulatory scrutiny, particularly as concerns regarding consumer welfare impacts intensify. The findings suggest that dominant carriers should proactively develop strategies for addressing potential regulatory interventions focused on maintaining competitive intensity.

For challengers and new entrants, the research identifies specific market categories where entry barriers have been reduced through incumbent retrenchment. The differentiated recovery patterns across leisure and business markets create targeted opportunities for specialized business models, particularly those focused on cost leadership in leisure-oriented segments.

Policymakers and regulatory authorities should note the accelerated concentration trends in specific markets and consider tailored interventions that address localized competitive concerns rather than applying uniform approaches across the industry. As Lee and Brown (2023, p. 517) argue, “the post-pandemic competitive landscape requires nuanced regulatory approaches that recognize the heterogeneous market structures emerging across different geographic and product segments.”

5.3 Limitations and Future Research Directions

This research has several limitations that suggest productive avenues for future investigation. The case study approach, while enabling detailed analysis of specific markets, limits generalizability to the global industry. Future research should extend this analytical framework to additional geographic markets, particularly emerging markets with distinctive institutional characteristics.

Additionally, the focus on capacity-based market share metrics may not fully capture competitive dynamics related to yield management and profitability. Future studies could incorporate more granular analysis of financial performance metrics to assess the relationship between market concentration and economic returns.

The ongoing nature of the industry’s recovery trajectory also suggests value in longitudinal extensions of this research. As market structures continue to evolve, repeated measurement of concentration metrics and strategic positioning would enable identification of longer-term competitive patterns and potential equilibrium states.

6. Conclusion

This case study of post-pandemic competitive dynamics in the airline industry reveals significant structural transformations that have important implications for understanding competition in network industries. The research documents accelerated concentration in specific markets, strategic bifurcation in pricing approaches, and systematic network reconfiguration that collectively constitute a fundamental reshaping of the competitive landscape.

The findings suggest that while traditional models of airline competition retain analytical value, they require modification to account for increasingly stratified competitive dynamics across market segments. The pandemic has not merely temporarily disrupted established competitive patterns but has catalyzed structural changes that will likely persist as permanent features of the industry landscape.

As the industry progresses through its recovery trajectory, continued monitoring of competitive dynamics will be essential for both theoretical advancement and practical strategy formulation. This research provides a foundation for such ongoing assessment while contributing to the broader understanding of how exogenous shocks reconfigure competition in complex network industries.
