This Is Europe’s Most Profitable Airline In 2025

Europe’s aviation industry is in remarkable shape in the mid-2020s, with airlines recovering strongly from the pandemic years and posting impressive profits. In our article, we look at the question: Which is Europe’s most profitable airline in 2025? The answer is not straightforward, as it depends on several factors. We’ll take a close look at three major carriers/groups: the ultra-low-cost specialist Ryanair Group , the legacy powerhouse International Airlines Group (IAG), which consists of several airlines, and the ambitious trans-continental player Turkish Airlines, and explain why they are Europe’s profitability champions.

While many eyes in Europe focus on short-haul budget wars or global alliances, profitability remains the ultimate yardstick. With rising fuel costs, supply chain delays, and increasing competition, airlines must be efficient, globally connected, and strategically well-positioned to succeed. In this piece, we provide background context on how each player is performing in low-cost, legacy group, or long-haul/intercontinental categories, and then make the special case study for Turkish Airlines, which takes the crown for profitability in 2025 (on a Europe-focused basis) when you exclude low-cost and break down a large group like IAG into its constituent airlines.

Ryanair: Europe’s Low-Cost Champion

Let’s start with Ryanair, the Irish ultra-low-cost carrier that has been one of the most profitable airlines in Europe in recent years. Ryanair specializes in high utilization, minimal frills, high load factors, and rigorous cost control.

According to its annual report, Ryanair recorded a profit after taxation of €1.92 billion in fiscal year 2024 on revenues of €13.44 billion, with a load factor of around 94%. The business model is finely tuned for the low-cost end: 183.7 million passengers, average fare up ~21% versus prior year, ancillary revenues rising, and operating expenses held in check.

Analysis from the consultancy Gridpoint Consulting shows Ryanair achieving top-tier pre-tax profit margins among European airlines thanks largely to its “rock-solid balance sheet with very little debt and lots of cash.” This margin performance makes Ryanair the standout in Europe’s low-cost segment. So, in short, for low cost, Ryanair wins and continues this trend throughout 2025 and is likely to continue in 2026 as well.

IAG (And Its Constituent Airlines): The Strongest Group

Next up is IAG, the parent group of airlines including British Airways, Iberia, Vueling, and others. Among large European airline groups, it has posted some of the strongest results.

Gridpoint’s tally shows IAG achieving pre-tax profits of €3.8 billion in 2024, placing it “top of the pile” among European airlines in absolute profit terms. Meanwhile, according to Yahoo! Finance, its operating margin for 2024 was reported at 13.8% and return on capital of 17.3%, which is really impressive for an airline business. When one looks at its constituent airlines, for instance, British Airways achieved 14.2% margin, Iberia 13.6%.

However, the picture changes when one wants to understand which singular airline is Europe’s most profitable: instead of considering groups, the correct approach is to split each group into its separate airlines. While IAG is clearly a top performer, it does not provide a single standalone airline with dominance in profitability (when compared to others such as Turkish). In other words, yes, IAG is very profitable, but, in this assessment, when isolating airlines, another unexpected player takes the crown.

Turkish Airlines: The Unexpected Legacy Champion

Now we turn to Turkish Airlines, the flag-carrier of Türkiye, which in 2024 posted around €2.06 billion (US$2.4 billion) net profit in challenging global conditions, and as such positions itself as Europe’s most profitable airline when you exclude the low-cost Ryanair and treat IAG as separate airlines.

Specifically, Turkish Airlines reported revenues of US$22.7 billion in 2024, up just over eight percent year-on-year. Cargo revenue grew by ~35%, passenger revenue by ~four percent, as per Aviation Week. Its Earnings Before Interest, Tax, Depreciation, Amortisation and Rent (EBITDAR) came to US$5.7 billion, with a margin of 25.3%.

Gridpoint also highlights that Turkish’s result benefited in part from ~US$1.7 billion of income from investment activities, boosting its profit figure. The cargo side in particular is becoming a major strength: Turkish Cargo increased annual cargo volume by over 20% and has become the world’s third-largest air-cargo carrier by IATA data, as reported by the Aviation Business News.

What makes Turkish Airlines especially compelling is its combined network scale, serving all continents and holding the Guinness World Record for the most destinations served globally, mainly from its hub in Istanbul, as well as its cargo strength and improving balance sheet. Moreover, given that Ryanair is low-cost (so outside the pure legacy full-service airline comparison) and IAG is a group of multiple airlines rather than a single entity, Turkish stands out as the most profitable single airline in Europe in our taxonomy and the winner of our classification as the single most profitable legacy airline in Europe.

Low-cost Vs. Legacy Vs. Network: Why The Distinction Matters

It’s worth considering why we make the distinctions: low-cost, legacy-group and individual airline when discussing “most profitable.” Because the business models differ significantly, profitability must be judged against appropriate peer sets.

Ryanair’s low-cost model thrives on minimal turnaround, maximized utilization, lean staffing, and ancillary revenue everywhere. That gives incredible margins in the short-haul European context. The legacy-group model (IAG) blends multiple airlines with different brands, hub networks, premium cabins, intercontinental traffic, and aircraft types —a complexity that offers opportunity but also creates cost drag. Finally, a single airline like Turkish blends full-service network operations with cargo and global reach in a way that gives it an edge beyond just being low-cost or purely local.

From the data we’ve reviewed: Ryanair leads the low-cost group; IAG leads among large legacy groups; but Turkish Airlines leads when you consider a single full-service airline (excluding low-cost) in Europe under the definition in our article.

Practical Takeaways for The Aviation Observer

So what does this mean if you’re an aviation strategist, investor, or simply an enthusiast trying to understand which European airline is ‘winning’ on profitability? You might ask: Which airline should I benchmark? Which model should I follow? Which player is demonstrating the greatest financial resilience?

Here are some considerations:

• If you are focused on the low-cost segment, Ryanair is the benchmark. It continues to deliver through cost leadership, strong revenue growth and load factors.
• If you look at large legacy airline groups, IAG is a star performer, showing that legacy brands can be cut-for-profit again.
• If you look solely at single airlines (excluding low-cost) and across all segments, Turkish Airlines emerges as the most profitable in Europe in a 2025-style measurement. That means it is the one to watch for network scale, cargo growth, and balance-sheet improvement.

For airline managers, this suggests that diversification of revenue base (cargo, long-haul), a strong hub network, disciplined cost management, and capital structure matter as much as being either super-low-cost or simply a legacy carrier. Turkish Airlines’ profile shows exactly that: combining volume, cargo growth, market access, and resilience. Investors should also note that profitability is not just about revenue growth but also about margins, capital returns, and debt reduction – all of which Turkish is doing well.

Finally, as we look beyond 2024 into 2025 and further, metrics such as load factor, fare pressure, fuel hedging, fleet delivery delays, and cargo market dynamics will be critical for maintaining profitability across European airlines.

For Ryanair: the most significant risks lie in fare erosion, aircraft delivery delays, and rising input costs. For IAG: success will hinge on premium traffic recovery, efficiency in network operations, and managing transition costs across brands. For Turkish Airlines, the challenge will be sustaining cargo growth, navigating geopolitical/regulatory risks, and continuing to manage debt while investing in its network. From the data, if Turkish can maintain its momentum and manage those headwinds, it’s positioned to remain Europe’s most profitable single airline.

In the broader industry context, profitability margins remain under pressure: one study noted that, even though global airline profits hit a record US$36.6 billion in 2024, the net margin was only around three and a half percent, meaning returns are still below the cost of capital, according to Gridpoint Consulting. So even the highest performers must stay vigilant. For Europe, especially, issues such as air-traffic control strikes, airport capacity constraints, the sustainability transition, and disrupted supply chains will keep the margin challenge real. If Turkish Airlines, Ryanair and IAG can navigate these successfully, they will remain at the top.
