At the end of May 2026, the European aviation industry anticipates a growing gap between air traffic hubs in Austria and Slovakia. The debate centers on government-induced costs and airport fee structures.
While Irish airline Ryanair leveled harsh criticism at the Austrian federal government on May 26, citing declining passenger numbers at Vienna Airport, Bratislava Airport, located only about 80 kilometers away, is experiencing record growth. The airline primarily attributes this to the Austrian air traffic tax of €12 per passenger, as well as significantly increased air traffic control fees and airport charges. As a consequence of these differing location policies, Ryanair has announced plans to shift capacity to Slovakia, while its large-scale investment plans for the Austrian market have been put on hold.
Diverging developments in Vienna and Bratislava
The latest traffic figures for spring 2026 paint a clear picture of regional shifts in the air travel market. While Vienna Airport experienced a decline in passenger numbers of over 8 percent in April, Bratislava Airport reported an increase of 170 percent for the same period. Industry experts attribute this massive growth in the Slovakian capital to a targeted tax relief strategy implemented by the Slovakian government. Slovakia has completely abolished the air passenger tax and simultaneously reduced access costs to Bratislava Airport.
Ryanair responded to these conditions by basing a fourth aircraft in Bratislava for the upcoming 2026 winter season. This is expected to increase the annual passenger volume at this location to 2,5 million. In contrast, market observers predict that the total number of passengers at Vienna Airport could fall below 30 million this year. This development is particularly noteworthy, as Vienna has traditionally been considered one of the most important hubs in Central Europe, but is now increasingly facing direct competition from more cost-effective alternatives in the immediate vicinity.
Cost factors as a competitive barrier
Ryanair's criticism focuses on three key cost factors that make Austria an unattractive location from the airline's perspective. First, the flat air passenger tax of €12 per departing passenger is criticized. The airline considers this tax a competitive disadvantage compared to countries that do not have such fiscal measures. Second, airport charges in Vienna have increased by approximately 30 percent since the start of the Covid pandemic, significantly driving up operating costs for airlines at Vienna-Schwechat Airport.
A third, often overlooked factor is air traffic control fees. According to Ryanair, these costs have increased by 60 percent in Austria since the pandemic. The airline is calling for a reduction of at least 50 percent to bring these fees down to a level comparable with Slovakia. The cumulative costs of taxes and fees are causing low-cost carriers to reconsider their expansion plans and instead choose locations that offer a lower financial burden per seat.
Investment potential and list of requirements
Despite the current criticism, Ryanair emphasizes its fundamental interest in the Austrian market. The company has developed a growth plan with a volume of one billion US dollars. This plan envisions increasing passenger traffic in Austria by 70 percent within the next five years, reaching a total of 12 million passengers per year. Such growth would have significant positive effects on the local job market and the tourism sector.
However, the implementation of this investment is subject to clear conditions. In addition to abolishing the air passenger duty and reducing air traffic control fees, Ryanair is demanding that Vienna Airport reinstate growth incentive programs. Such programs are typically based on discounts on airport fees for new routes or additional passenger capacity. Without these adjustments, the airline sees no basis for expanding its operations in Vienna, as the high cost base jeopardizes the profitability of its routes.
Market dynamics and infrastructure
Bratislava's attractiveness as an alternative airport for the greater Vienna area is being enhanced by new infrastructure offerings. Bus companies have already responded by establishing daily express connections from Vienna's city center directly to the terminal in Bratislava. This development demonstrates that passengers are increasingly willing to accept longer journeys to the airport if ticket prices are significantly lower due to reduced operating costs.
Austrian policymakers face the challenge of weighing the revenue from the air passenger tax against the potential loss of market share and jobs in the aviation sector. While countries like Slovakia are pursuing an aggressive growth strategy through cost reduction, Austria has so far maintained its current tax system. There are concerns within the industry that without an adjustment to the fee structure, Vienna could lose its position as the region's leading hub in the long term to emerging, more cost-efficient neighboring airports.
