The aviation industry is facing a seismic shift as Aer Lingus follows Ryanair, Wizz Air, Avelo, and American Airlines in a devastating move: a wave of base closures that is sending shockwaves across the globe. These closures are sparking a global aviation crisis, disrupting travel, jobs, and local economies. But what is driving these drastic decisions? Increased taxes, airport fee hikes, and rising operational costs have all played a significant role in forcing airlines to rethink their strategies. The low-cost carriers that once thrived on budget-friendly fares are now grappling with unsustainable expenses, forcing them to scale back operations.
This article delves into the reasons driving airlines to shutter bases, the broader economic impacts, and the resulting ripple effects on travel, jobs, and tourism. Buckle up as we uncover the hidden forces shaking up the skies and redefining how we fly.
Ryanair, Europe’s largest budget airline, has long thrived on its ability to offer affordable flights by cutting costs at every turn. However, in January 2025, Ryanair shocked Denmark by announcing the closure of its Billund base and the cancellation of all routes to and from Aalborg. Why? A new aviation tax of up to DKK 50 per passenger departing from Denmark was introduced, which Ryanair deemed unsustainable for its low-cost model. This tax increase not only forced the airline to cut 32 routes and two aircraft but also served as a warning shot to other countries contemplating similar taxes. Passengers, who once enjoyed cheap flights from Billund, are now left scrambling for alternative options. This tax hike highlights a larger issue: how even minor tax changes can have major consequences for air travel, local economies, and tourism.
Portugal was the next battleground for Ryanair. In December 2023, Portugal’s regulator, ANAC, approved airport fee hikes of up to 17%, leading Ryanair to reduce its operations in Faro and Porto and close its base in Ponta Delgada in the Azores. For Ryanair, which prides itself on operating with ultra-low costs, the price hikes made it impossible to sustain its operations in these regions. The airline blamed Portugal’s airport monopoly for the excessive charges and warned that such increases could have a detrimental impact on local economies and tourism. The loss of Ryanair’s base in Ponta Delgada, coupled with the company’s capacity reductions, is a stark reminder of how rising infrastructure costs can push airlines out of regional markets.
Wizz Air, another European low-cost giant, faced similar challenges. In September 2025, the airline made the decision to close its base in Vienna, citing rising airport costs and taxes that no longer aligned with its low-cost business model. Wizz Air had launched the Vienna base just a few years earlier, in 2018, to cater to growing demand in the region. However, by 2025, increasing fees and taxes made the base unprofitable, prompting the airline to withdraw its services to cities like Bilbao and London Gatwick. This closure underscores how sensitive low-cost carriers are to small increases in operational costs, and how these carriers continually adjust their network strategies to focus on the most profitable markets .
In the U.S., Avelo Airlines has joined the ranks of carriers adjusting their networks due to financial pressure. In early 2026, Avelo announced a major network overhaul that included the closure of several bases, including Mesa, Arizona; Raleigh-Durham, North Carolina; and Wilmington, North Carolina. These closures were part of Avelo’s strategy to streamline operations and focus on its most profitable hubs. Despite being a newer carrier, Avelo’s decision to shut down multiple bases highlights the difficult balancing act between growth and cost control. With the airline’s decision to retire older aircraft and close non-profitable bases, passengers in these regions will see reduced services or need to travel further to board flights. This restructuring comes as part of Avelo’s broader effort to ensure long-term sustainability and profitability .
American Airlines, a legacy carrier with deep roots in U.S. aviation, made waves in 2022 with its decision to close its flight-crew base at San Francisco International Airport (SFO). This move, which affected 400 flight attendants, demonstrated that even major airlines are not immune to the pressures of cost management and network rationalisation. American shifted the crew base to other hubs, forcing employees to either relocate or endure long commutes. While the closure did not directly reduce flight frequencies, the shift highlighted the operational changes airlines must make to align their staffing and resources with market demand .
In the UK, Aer Lingus has thrown its Manchester base into uncertainty. In late 2025, the airline paused sales for its long-haul transatlantic routes from Manchester to New York, Orlando, and Barbados, leaving passengers uncertain about the future of these services. The official line from Aer Lingus was that it was undergoing a period of uncertainty regarding its Manchester operations, and it stopped selling tickets for travel after March 2026. While the closure hasn’t been confirmed yet, the pause in ticket sales signals that the airline is considering scaling back its presence at this base. This potential closure adds to the growing trend of airlines reassessing their operations in smaller markets, particularly in the face of rising operating costs .
The economic consequences of these base closures are far-reaching. When an airline shuts down a base, it doesn’t just affect passengers — it also disrupts the livelihoods of airline staff, ground crew, and the broader local economy. In Billund, for example, Ryanair’s departure cut 1.7 million seats and 32 routes, weakening the region’s connectivity to other European destinations. Similarly, the closure of Avelo’s bases in Mesa, Raleigh-Durham, and Wilmington will directly impact employees and local support services, including hotels, taxis, and other travel-related businesses. Job losses and service reductions create a ripple effect that can dampen local tourism and strain community resources.
Base closures also leave passengers scrambling for alternatives. Ryanair, for example, informed customers about the Billund closure, offering refunds or alternative travel options. However, these closures cause significant disruption for passengers who are now forced to rebook flights or seek out other carriers. Wizz Air and Avelo similarly offered refunds and rebooked passengers on other flights, but the inconvenience and uncertainty caused by such sudden changes can be frustrating for those whose travel plans are disrupted. Airlines must tread carefully in their communication with customers to avoid reputational damage and maintain customer loyalty .
Government policies, particularly those regarding taxes and airport fees, have played a pivotal role in triggering these closures. Denmark’s aviation tax, which Ryanair cited as the primary reason for its Billund exit, serves as a cautionary tale for policymakers. While governments seek to increase revenue through taxes, the resulting cost increases can drive airlines away, weakening connectivity and stalling tourism. Similarly, Portugal’s airport fee hikes led Ryanair to shut down its operations in the Azores. These closures reveal how sensitive low-cost carriers are to changes in government policies and how such policies can have far-reaching consequences for airlines, passengers, and local economies.
As base closures continue to unfold, they signal a shift in the low-cost aviation model. Carriers like Ryanair and Wizz Air, which have long relied on aggressive cost-cutting strategies, are now facing the limits of these models as rising fees and taxes eat into profitability. However, these closures also offer opportunities for airlines to consolidate their networks and focus on more profitable markets. For instance, Wizz Air’s retreat from Vienna and Avelo’s overhaul of its network demonstrate how airlines are rethinking their strategies to ensure long-term sustainability. As airlines adapt to these changes, passengers will need to be more flexible, as the landscape of global air travel continues to evolve .
The closure of airline bases marks a turning point in the aviation industry. Rising taxes, increasing fees, and changing market dynamics are forcing even the most cost-effective airlines to reassess their operations. As we’ve seen from Ryanair’s departure from Denmark to Wizz Air’s pullback from Vienna and Avelo’s restructuring, the skies are undergoing a fundamental transformation. For passengers, these closures mean fewer travel options and greater uncertainty. For airlines, they represent a necessary recalibration of networks to remain profitable in an increasingly expensive landscape. In the coming years, travellers and local communities will need to adapt as the aviation industry continues to evolve, reshaping the way we fly and the connections that bind us together.
