Turkish Airlines rejects claims of a complete suspension of flights to Iran, but some departures have still been cancelled
At a time when messages are spreading on social media about an alleged suspension of all Turkish Airlines flights to Iran, the company says these are inaccurate interpretations and that daily services are still operating as planned. Based on checks of available posts and schedules up to 1 March 2026, no decision to fully halt traffic on all routes to Iran has been confirmed. According to information available from the carrier and data that can be verified in ticket sales systems, flights to Tehran have not been collectively cancelled, and tickets are still available for purchase. However, ahead of and during heightened regional tensions, individual cancellations were recorded, especially in evening time slots, which some passengers experienced as a broader traffic stoppage. The company has so far not cited a single reason for all individual cancellations, but in practice such changes most often follow security assessments, changes to airspace regimes and operational adjustments on the ground. In such circumstances, information changes quickly, so the impression of a “complete suspension” can be created after just a few cancellations in a row.
From rumours to an official denial
A wave of posts on social media, including claims that Turkish Airlines “stopped all flights to Iran”, appeared on days when individual departures on the Istanbul–Tehran route were being cancelled at the same time. In such an information environment, where fragments of data from airport apps or from flight-tracking systems are shared without context, the boundary between a one-off cancellation and a broader suspension of traffic can easily blur. Turkish Airlines therefore emphasizes that daily flights to Tehran continue to operate and that ticket sales have not been blocked. This is an important distinction because a complete suspension implies closing sales and removing the route from the schedule, whereas operational changes most often involve selected flights at certain times or on certain days. In aviation, such corrections are often made “on the fly”, depending on risk assessment and slot availability.
In practice, passengers usually notice the change only when they receive a cancellation notification or when the status “cancelled” appears in the app. That is why companies in such situations often remind passengers that the most reliable channel to check flight status is the official website and the “Manage Booking” system, where current changes, offered alternatives and refund rules are visible. In its publicly available information on traffic irregularities, Turkish Airlines states that a change in departure time or a cancellation may occur for operational reasons or due to extraordinary circumstances, with the possibility of rerouting, changing the date or refunding in line with fare rules and passenger rights. This is standard practice in the industry, but in periods of heightened tensions the number of such interventions in the schedule usually increases.
What is known about the cancelled flights
According to reports from several media outlets and checks based on schedules at Istanbul Airport, on certain days in late February 2026 several flights between Istanbul and Tehran were cancelled. In some cases these were Turkish Airlines flights, and cancellations by Iranian carriers on the same route are also mentioned. It is important to stress that the mere fact of cancellations does not automatically prove a broader suspension, especially when on the same day or the following morning some other flights remain in the schedule. It is common practice that during a deterioration of the security situation, evening or night waves of departures are cut first, when crews and aircraft are less flexible for quick changes, and then traffic is reorganized in daytime windows considered more stable. An additional problem is that a cancellation can also occur on the opposite rotation, so the effect carries over across the entire day, including connections.
Available flight schedules for the Tehran (Imam Khomeini) – Istanbul route show that this is one of Iran’s more frequent international links with Europe, with multiple departures per week and with Istanbul’s role as a transit hub. Because of that, even partial cuts on that route quickly create a “chain reaction” effect: passengers traveling from Tehran to Europe, North America or onward to Asia via Istanbul lose connections, and pressure on alternative services grows. In such circumstances, the number of requests to change the travel date, change the route or obtain a refund usually increases, and some passengers switch to other carriers or to flight combinations with longer layovers. Passengers with a single short connection are particularly sensitive, because even a small change in departure waves can “collapse” the entire travel plan.
Regional tensions and airspace as the key risk
Cancellations and schedule changes are happening in the broader context of a sudden deterioration of the security situation in the Middle East. According to international media, in late February 2026 U.S. and Israeli military strikes were recorded against targets in Iran, followed by countermeasures and a wave of airspace closures or restrictions in multiple countries. Such a situation directly affects civil aviation because routes that normally pass over Iraq, Syria, Iran or Gulf states can become unavailable or risky, forcing carriers onto detour corridors. Detours mean longer flight times, higher fuel burn, possible technical landings and crew-scheduling constraints, all of which increase the likelihood of individual rotation cancellations. In extreme situations, when the airspace regime changes in a short time, companies are forced to “cut” some flights so that fleets and crews can return to a sustainable schedule.
On days when large segments of airspace are closed, even the biggest airlines introduce extraordinary measures: they temporarily suspend certain routes, reroute aircraft onto safer paths or cut frequencies to reduce exposure for crews and passengers. Media reports speak of thousands of cancelled or delayed flights and strong pressure on regional hub airports, especially those in the Persian Gulf. In such an environment, even though Turkish Airlines says daily flights to Tehran are continuing, a few cancellations in a short period are enough to create the impression of a broader suspension, especially among passengers who planned an evening departure or a connection. An additional difficulty is that passengers often track only their flight number, not the overall traffic pattern, so they conclude on the basis of a limited sample.
Diplomatic warnings and changes in passenger behaviour
In parallel with changes in air traffic, U.S. diplomacy has warned citizens through its channels about increased security risks in the region, and Iran has long been at the highest “do not travel” advisory level in the U.S. travel advisory system. At moments of escalating tensions, such messages are reinforced with additional notices and calls to follow local guidance, which also has a practical consequence: some passengers postpone trips, while others try to return as soon as possible or change their route. Airlines typically communicate that flight status can vary hour by hour, depending on NOTAM notices, decisions by competent aviation authorities and risk assessments that are constantly updated. That is why even information that “daily flights continue” does not mean that every rotation will be stable, especially if security assessments change.
Such events further highlight Istanbul’s role as a transit centre where passengers from Europe, Iran and the wider region meet. When just one link in the chain is disrupted, for example an evening flight from Istanbul to Tehran, the consequences spill over to morning connections, aircraft rotations and crew availability. Passengers are then offered rebooking on the next available flight, but in periods of general instability capacities fill up quickly and alternatives become more expensive or less convenient. In that sense, Turkish Airlines’ denial does not mean the schedule will be completely immune to further changes, but that there is no decision on a complete and permanent suspension of traffic to Iran across all time slots. For readers and passengers, the key difference is between “cancelling a route” and an “operational reduction” that can change from day to day.
What passengers can expect: changes, refunds and replacement options
When a flight is cancelled, the usual scenarios are changing the date, rerouting via other destinations or a refund, depending on the fare and on whether the situation is declared extraordinary. In its publicly available guidance, Turkish Airlines states that changes and refunds can be handled through digital channels, noting that extraordinary circumstances may affect conditions and any fare differences. In such situations passengers most often seek three things: quick transfer to the first next flight, clear information on the right to a refund or voucher, and confirmation of the status of connections if they purchased the entire itinerary on one ticket. Operationally, carriers try to protect connection “banks” at hubs, but when airspace is disrupted or slot restrictions arise, priorities shift quickly.
To avoid additional costs and stress, passengers are usually advised to check flight status on official channels before going to the airport, to prepare flexible options for connections, and to allow for possible delays in baggage and security procedures. In periods of airspace restrictions, the number of “technical” changes also increases: aircraft fly longer routes, sometimes the aircraft type changes, and crews operate under a regime where duty-time limits are strictly controlled. All of this makes the schedule more sensitive to a domino effect, where a delay on one flight turns into the cancellation of the next. Ultimately, the passenger experience on such days depends on the speed of communication and the airline’s capacity to offer a realistic alternative, not just a formal possibility of change.
The bigger picture: how the aviation industry copes with a crisis
In crises of this type, the aviation industry operates on the principle of “safety first”, but also with a constant need to maintain minimum connectivity. In a region where political and security developments are fast-moving, carriers rely on assessments by security services, information from aviation authorities and operational analyses from their control centres. When restrictions are short-lived, airlines often choose a partial approach: they keep some daily frequencies, while temporarily cutting riskier waves of departures. That very pattern—continuing daily flights while cancelling certain evening ones—fits the explanation Turkish Airlines gives in denying claims of a complete suspension. For passengers and the public, however, it remains a sensitive topic because in practice the line between a partial reduction and a broader traffic stoppage is very thin.
At the same time, competing airlines and regional carriers in similar situations sometimes make different decisions, depending on fleet, route and exposure to particular airspaces. In practice this means passengers may see a very uneven picture: one carrier flies, another temporarily does not, a third flies but reroutes and introduces longer travel times. In such circumstances even reliable information becomes outdated quickly, so caution is recommended toward viral posts that do not distinguish individual cancellations from a formal route suspension. For passengers planning travel to Iran or transit via Tehran, it is crucial to follow official notices, because airspace regimes and risk assessments can change from day to day. Until the regional situation stabilizes, it is realistic to expect the schedule to remain subject to rapid corrections, even if airlines do not formally declare a general suspension.
