You were hurt on a Turkish Airlines flight, probably on the long leg between California and Istanbul, and you are trying to work out whether anything can be done about it from here. The short version is that the law is more favorable to you than it looks, and the deadline is shorter than it feels.

Does the Montreal Convention Cover a Turkish Airlines Flight?

Yes, on any normal itinerary between California and Istanbul. The treaty governs international carriage between countries that are parties to it, and both the United States and Turkey are parties. A ticket from Los Angeles or San Francisco to Istanbul, or onward through Istanbul to somewhere else, is international carriage from the first segment to the last.

That answer matters more than it sounds, because the treaty is not the restriction most passengers assume. Below a threshold set by the treaty, Turkish Airlines is not permitted to argue that it was not at fault for an injury caused by an accident on board. Above that threshold it can defend itself, and if it cannot prove it took all reasonable measures, nothing caps what it owes. You start from a stronger position than you would in an ordinary negligence case against anyone else.

Can You Sue Turkish Airlines in California?

Often you can, and you should not assume Istanbul before anyone has looked at it. The treaty gives passengers injured on international flights a forum where they have their principal and permanent residence, provided the airline operates service to or from that place and does business there from premises it or a commercial partner occupies.

Several factors determine whether those conditions were met on your particular trip. They include where you actually lived on the date of the flight, the service the airline was operating to or from California around that time, and the kind of presence it kept in the state. Those things move, so this is a question to check against your itinerary rather than answer from a web page. Send us the booking and we can review where your case can be brought. When the conditions are satisfied, it ordinarily means federal court in California: local counsel, local discovery, and a jury drawn from where you live rather than a proceeding in Istanbul conducted in a language you may not read.

The Istanbul Connection Changes the Math

This is the part specific to Turkish, and it is the reason the residence forum matters more here than it does for most carriers.

Istanbul is a transfer hub rather than a destination for most passengers who fly there from California. Turkish Airlines reaches more countries from that single airport than almost any other airline does from anywhere, which means a large share of its California passengers are not going to Turkey at all. They are going to Tbilisi, or Nairobi, or Tashkent, with a four-hour layover in between.

Hold the treaty's standard forum options against that itinerary. The airline's home and principal place of business are in Turkey. The destination may be a third country. The place the contract was made may be California, or may be wherever the booking site is legally seated. On a connecting itinerary, several of those options can point away from California, which is why the residence forum tends to carry more weight for a Turkish Airlines passenger than for someone flying a simple round trip.

That makes it worth establishing carefully and early rather than late. We go through how the forum works, and the situations where it closes, in suing a foreign airline in California, and we are glad to look at your own itinerary and tell you what is open.

Ownership, and Whether a Jury Hears It

One structural question gets overlooked until late, and Turkish sits in a more interesting position on it than the carriers it usually gets grouped with.

Under US law, an airline a foreign government owns or controls can be treated as an arm of that state. Where that applies, the claim may be tried to a judge rather than a jury, service of process runs through a particular route, and the whole case takes a different shape. Some of the Gulf carriers a California traveler might otherwise fly are government owned and the question is straightforward for them.

Turkish is not straightforward. A Turkish state fund holds a significant stake in the airline while the rest trades publicly, and the state's rights in the company are not limited to the shares it holds. There are also two routes to treating a company as an arm of a foreign state, one that looks at ownership and one that weighs government control, so counting shares does not necessarily end the analysis.

The honest answer is that this is genuinely arguable on Turkish rather than settled in either direction, and the figures involved change, so it is not something to resolve from a page like this one. It is worth raising at the outset of a case rather than at the end, because the answer shapes service of process, the forum, and whether a jury ever sees the file.

Who You Actually Contracted With

Turkish is a Star Alliance member, and that creates the most common identification problem in these claims. A passenger books on a US partner's website, sees that partner's flight number on the itinerary, and then boards an aircraft with Turkish crew and Turkish livery. A passenger going the other direction books with Turkish and flies a domestic US segment on partner metal.

The treaty distinguishes the airline that sold you the ticket from the airline that operated the flight, and lets a claim proceed against either. You need to know which is which, and your boarding pass will not reliably tell you, because the flight number on it often belongs to the seller rather than the operator. The booking confirmation with the operated-by line is the document that answers it. Find it before anybody talks to a claims department.

What injures passengers

Common Injuries on the Istanbul Run, and Which Ones the Treaty Reaches

The treaty reaches an injury caused by an accident, meaning an unexpected event external to you. That distinction decides most of these cases.

Overhead Bin and Falling Baggage

A bin that opens in flight, or a bag coming down during deplaning. External, and the clearest case the treaty handles.

Hot Liquid and the Service Cart

Scalding tea or coffee, or a cart striking a shoulder in the aisle. The cabin is under service for most of the day.

Turbulence

An unbelted passenger thrown from a seat. External. Whether the belt sign was on, and what the crew announced, usually matter.

Jetway and Airstairs Falls

Inside the treaty, because embarking and disembarking are part of the carriage. The jetway and the airstairs both count.

A Fall Inside the Terminal

Outside the treaty. A fall inside Istanbul Airport is a premises claim in Turkey, often on a much shorter deadline. Do not let it sit.

Clots, Cardiac Events, and Back Injuries

The hard category. The airline's answer is that your own condition surfaced on an ordinary flight, and it has been difficult to overcome.

Where We Are Not the Right Call

Four situations, and they come up often enough to be worth stating plainly rather than burying.

If you do not live in California, the residence forum follows your home rather than your airport, and you want counsel where you actually live. If you were hurt in the Istanbul terminal while connecting rather than on the aircraft or the jetway, that is a premises claim in Turkey and not a treaty claim, and it is not ours. If more than two years have passed since the flight landed, the claim is very probably gone, because that deadline is a condition on the right to sue and negotiating with the airline does not pause it. And if what you lost is a suitcase, handle it through the airline's own baggage process inside its notice window, which is counted in days. It is a form, not a case.

What to Do This Week

One. Pull the booking confirmation, not the boarding pass, and identify which airline sold the ticket and which one operated the flight you were hurt on.

Two. Write down the sequence while you still have it, focused on the external event. What moved, what fell, what was handed to you, which crew member you told, what they said, whether anything was logged.

Three. See a physician now rather than when it worsens. The gap between the flight and the first medical record is the argument every airline makes, and on a long-haul injury it is the argument Turkish will make too.

Four. Count two years forward from the landing date and treat it as fixed, whatever the claims department tells you about reviewing your file.

If you live in California, you were hurt by something that happened to you on the aircraft, and you are inside two years, the place to start is a conversation about where the claim can be brought and what the injury documentation actually supports. We evaluate these claims at no cost. If the answer is that your case belongs in Turkey, or that what happened does not meet the treaty's accident standard, we would rather say so in the first conversation than a year into one.
