Can You Sue a Foreign Airline in California?

You live in California. You were hurt on a flight operated by an airline headquartered eight thousand miles away, incorporated under laws you have never read, with a legal department in a city you connected through once. The obvious fear is that pursuing it means pursuing it over there.

Can I Sue a Foreign Airline in California?

Often you can, and you should not assume otherwise before anyone has looked at it. The treaty governing international flights contains a provision written specifically to give injured passengers a forum at home. Several factors decide whether it is open on your particular trip, and they are worth going through before you accept that your claim belongs overseas.

This is worth sitting with, because it runs against how passengers think about treaties. The Montreal Convention is generally described to travelers as a set of restrictions. On this question it does the opposite: it grants a right to sue at home that would not otherwise exist. Under the older treaty it replaced, a passenger in your position frequently had to litigate in the carrier's home country, and a great many valid claims died of that fact alone.

The Four Places Anyone Can Sue

The treaty gives every passenger four choices of forum. You can sue where the airline is domiciled, where it has its principal place of business, where the contract of carriage was made, or at the place of destination.

Those four do real work in some cases and nothing in others. If you bought your ticket in California, the place of contract may be here. If California was your final destination on the return, destination may be here. But for a California resident hurt on the outbound leg of a trip to Asia or Europe, all four can easily point abroad, which is exactly the gap the fifth option exists to close.

The Fifth Place, and Why It Is the One That Matters

For claims involving death or bodily injury, and only those, the treaty adds a fifth forum: the place where the passenger has their principal and permanent residence.

It comes with conditions, and all of them have to be satisfied. The airline has to operate passenger service to or from that place, either on its own aircraft or on a commercial partner's. And it has to do business there from premises that it or that partner occupies.

Whether a given airline meets those conditions is a factual question. It turns on the service that carrier was operating to or from California around the date of your flight, and on the kind of presence it keeps in the state. Both of those things move, which is why this is something to check against your itinerary rather than assume from a list. It does not take long to check. Send us the itinerary and we can tell you whether that fifth forum is open on your trip. When the conditions are satisfied, the case can go forward in federal court in California, which is where you want it: local counsel, local discovery, a jury pool drawn from where you live, and a court that applies the treaty every year.

There is one piece of fine print worth knowing, because it decides cases. The fifth forum applies to injury and death claims. It does not extend to a baggage or delay claim, which lives on the first four options only.

When California Is Not Available

Three situations take it away, and they are common enough that this section is not a formality.

If the airline does not serve California at all, and you reached it by connecting through another country, the residence forum generally does not open. The treaty asks whether the carrier operates to or from your home, and if the answer is no, the honest answer to your question is that your case belongs in the carrier's home country and you need counsel there rather than here.

If your principal and permanent residence was not California at the time, the forum follows the residence, not the ticket. Students, people mid-relocation, and dual residents all need a closer look at this than a web page can give.

And if the carrier's home country is party only to the older treaty rather than the newer one, the fifth forum may not exist for that carrier at all. This is rare among the airlines most Californians fly, but it is precisely the kind of question to resolve early rather than late, because resolving it late means resolving it after a deadline has run.

Which Airline Are You Actually Suing?

A related question gets missed constantly. When one airline sells the ticket and another operates the aircraft, the passenger often has a contract with one and an injury caused by the other, and the treaty generally lets the claim proceed against either.

That matters here because the two carriers may not share a forum. Identifying both, early, is part of the work, and it starts with the booking confirmation rather than the boarding pass, which often carries the selling airline's flight number rather than the operating airline's.

What This Does Not Fix

Winning the forum question is not winning the case, and a California courtroom does not change what the treaty allows.

The claim is still governed by the treaty rather than California law, which means no punitive damages and no parallel state negligence claim. You still have to show that what happened to you was an accident in the treaty's sense, meaning an unexpected event external to you rather than your own medical episode. And the two-year deadline runs on the same schedule regardless of which country you file in, without stopping while anybody negotiates. If you are not sure the treaty covers your injury in the first place, start with what the treaty actually means for an injured passenger.

What to Do

One. Pull the booking confirmation and identify two things: which airline sold you the ticket, and which one operated the flight you were hurt on.

Two. Note your residence on the date of the flight. Not now. Then.

Three. Check the date the flight landed and count forward two years. That is the only date in the file that cannot be negotiated.

If you live in California and were hurt on an international flight, the useful first step is finding out where your case can actually be brought. Several factors determine that, and we would rather go through them with you against your real itinerary than have you guess from a web page. The other questions, whether what happened qualifies as an accident and what it actually cost you, are worth a conversation before the airline's claims department shapes the record. We handle these claims and the first evaluation is free. If the answer turns out to be that your case belongs in another country, we will tell you that instead of taking a year to get there.
