• US-Turkey open skies agreement exists; absence of US flights is commercial, not regulatory.

This analysis examines why no US airline currently operates nonstop flights between the United States 🇺🇸 and Istanbul, despite the city’s importance as a global travel hub and the strong presence of Turkish Airlines. The purpose is to provide a clear, evidence-based understanding of the commercial, regulatory, and strategic factors shaping this unique transatlantic air travel market.

Methodology

This content draws on official airline schedules, public statements, government agreements, and industry data as of June 2025. It synthesizes quantitative data (such as the number of nonstop flights, airlines, and destinations) with qualitative analysis from industry experts and stakeholders. The findings are presented with visual descriptions, comparative tables, and clear explanations of trends and patterns. All information is sourced from publicly available records, airline websites, and government resources, ensuring accuracy and transparency.

Key Findings

• No US airline currently operates nonstop flights to Istanbul. Turkish Airlines is the only carrier offering direct service between the United States 🇺🇸 and Istanbul, serving at least 14 major US cities.
• There are no regulatory barriers. The US and Turkey have an open skies agreement, so the absence of US airline service is a commercial decision, not a legal or diplomatic one.
• Turkish Airlines dominates the market. Its extensive US network, competitive pricing, and strong connecting hub in Istanbul have made it difficult for US airlines to compete.
• US airlines prioritize other markets. United, Delta, and American focus on routes where they have stronger alliance partners and more profitable business traffic.
• Travelers have limited nonstop options. US travelers must fly Turkish Airlines for nonstop service or connect via European hubs on US or European carriers.
• No imminent changes are expected. As of June 2025, no US airline has announced plans to launch nonstop service to Istanbul.

Comparisons, Trends, and Patterns

Historical Context

• Pre-2016: US airlines, including Delta, occasionally operated nonstop flights to Istanbul.
• 2016: Delta suspended its Istanbul service, citing security concerns and weak demand.
• 2016–2025: Turkish Airlines rapidly expanded its US service, filling the gap and establishing a near-monopoly on nonstop US-Istanbul flights.

Pattern:
Since 2016, Turkish Airlines has steadily increased its US presence, while US airlines have not returned to the nonstop market. This trend reflects a shift in strategic priorities and market realities.

Competitive Dynamics

Turkish Airlines’ Advantages:

• Extensive US network: Serves more US cities nonstop than many European carriers.
• Strong connecting hub: Istanbul’s location allows for efficient connections to Europe, Asia, Africa, and the Middle East.
• Government support: Turkish Airlines benefits from national backing, helping it compete aggressively on price and frequency.
• Star Alliance membership: While United is also in Star Alliance, Turkish Airlines’ dominance in Istanbul gives it a unique advantage.

US Airlines’ Challenges:

• Lack of alliance synergy: Istanbul is not a major hub for US airline alliances, limiting partnership opportunities.
• Commercial priorities: US airlines focus on more profitable routes (e.g., London, Paris, Frankfurt, Asia) where they have stronger business traffic and alliance partners.
• Historical precedent: Past attempts to serve Istanbul nonstop were not profitable or sustainable.

Codeshare and Connecting Alternatives

US airlines offer connecting service to Istanbul through European partners:

• United: Connects via Lufthansa (Frankfurt, Munich), Swiss (Zurich), or Austrian (Vienna).
• Delta: Connects via Air France (Paris) or KLM (Amsterdam).
• American: Connects via British Airways (London) or Iberia (Madrid).

Visual Description:
Picture a traveler flying from Chicago to Istanbul. Instead of a direct flight, they might fly Chicago to Frankfurt on United, then Frankfurt to Istanbul on Lufthansa. This two-step journey is common for US airline customers.

Evidence-Based Conclusions

Why Don’t US Airlines Fly Nonstop to Istanbul?

1. Competitive Disadvantage and Market Saturation

Turkish Airlines has built a strong position on US-Istanbul routes, offering more flights, better connections, and lower prices than US airlines could match. Its aggressive expansion and government support have made it hard for US carriers to compete profitably.

2. No Regulatory Barriers

There are no legal or diplomatic obstacles. The US and Turkey have an open skies agreement, which means airlines from both countries can operate as many flights as they want between the two nations. The decision not to fly is purely commercial.

3. Aircraft and Hub Strategy

US airlines have chosen to focus their long-haul aircraft on routes where they have stronger alliances and more business travelers. Istanbul does not fit into their main alliance networks, making it less attractive.

4. Historical Precedent

Delta’s suspension of Istanbul service in 2016, due to security and demand issues, set a precedent. Since then, no US airline has found a compelling reason to return.

5. Codeshare and Connecting Alternatives

By partnering with European airlines, US carriers can still serve Istanbul passengers without the risk and cost of operating their own nonstop flights.

Practical Effects on Travelers

• Nonstop flights: Only available on Turkish Airlines.
• Connecting flights: Available on US and European carriers via major European hubs.
• Frequent flyer benefits: Limited for US airline customers unless they are Star Alliance members (e.g., United MileagePlus).
• Fares and schedules: Turkish Airlines sets the pace on nonstop routes, but competition from connecting flights helps keep prices reasonable.

Step-by-Step: How to Book a US-Istanbul Flight

1. For nonstop service: Book directly with Turkish Airlines at turkishairlines.com.
2. For connecting service: Book with a US or European carrier, connecting via a major European hub (e.g., Frankfurt, Paris, London).
3. For Star Alliance benefits: Book Turkish Airlines or United codeshare flights (note: United does not operate its own aircraft on these routes).

Multiple Perspectives

Turkish Airlines Perspective:
The US is a key growth market. Turkish Airlines has invested heavily in expanding its US network, using Istanbul’s location as a global hub to attract travelers from all over the world.

US Airlines Perspective:
The Istanbul market is tough. Turkish Airlines’ dominance, lack of alliance partners, and limited profitability make it a low priority compared to other transatlantic routes.

Travelers’ Perspective:
There are plenty of nonstop options on Turkish Airlines, but no US carrier means fewer choices for loyalty programs and US-style service.

Industry Analysts:
Turkish Airlines’ government support, cost structure, and network strategy explain its success and the lack of US competition. As reported by VisaVerge.com, these factors combine to create a market where US airlines see little incentive to compete directly.

Limitations

• No recent public statements: US airline executives and US Department of Transportation officials have not commented on future plans for Istanbul service.
• Market conditions may change: If demand increases, alliances shift, or new aircraft make the route more profitable, US airlines could reconsider.
• Data as of June 2025: The analysis reflects the situation at this time; future developments could alter the landscape.

Conclusion and Practical Guidance

No US airline currently flies nonstop to Istanbul. Turkish Airlines remains the sole operator, thanks to its strong network, government support, and strategic focus on the US market. US airlines have chosen to focus elsewhere, relying on codeshare and connecting flights to serve Istanbul-bound passengers. Unless there is a major shift in demand, alliances, or aircraft economics, Turkish Airlines is likely to keep its monopoly on nonstop US-Istanbul flights for the foreseeable future.

Actionable Takeaways:

• Travelers seeking nonstop flights to Istanbul must book with Turkish Airlines.
• US airline customers can reach Istanbul via connecting flights through European hubs.
• For frequent flyer benefits, consider Star Alliance options or codeshare flights.
• Monitor airline announcements for any future changes, but no new US-operated nonstop service is expected soon.

This situation highlights the complex mix of commercial strategy, market dynamics, and international aviation policy that shapes global air travel options. For the latest updates, travelers should check official airline and government websites before booking.
