You were hurt on a Copa Airlines flight, almost certainly on a trip that connected through Panama City on the way to somewhere else in Latin America. That connection is not a detail. It is the thing that decides where your case can be heard.

Does the Montreal Convention Cover a Copa Flight?

Yes. Panama ratified the treaty early and the United States has been a party since 2003. The treaty governs international carriage between parties, and the test is the itinerary you bought rather than the leg where the injury happened, so a ticket from Los Angeles through Panama City to Bogota is international carriage from the first segment to the last.

Below a threshold the treaty sets, Copa is not permitted to argue 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. The figure in the treaty is a floor under the claim rather than a cap on it.

Why Your Residence Does All the Work Here

This is the part specific to Copa, and it is the strongest reason this page exists separately from a general treaty explainer.

Copa is built almost entirely around a single connecting hub. Panama is not where its California passengers are going. It is where they change planes on the way to Colombia, Peru, Brazil, Argentina, or a dozen smaller markets. Very few people fly from California to Panama and stop there.

Now hold the treaty's standard forum options against a typical Copa itinerary. The airline's domicile and principal place of business are in Panama. The place of destination is often a third country in South America. The place where the contract was made may be California, or may be wherever the booking platform 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 on this carrier than on one you fly round trip.

That forum is available for injury and death claims at the passenger's principal and permanent residence, provided the carrier operates service to or from that place and does business there. Whether it is open on your trip depends on several factors, including the service Copa was operating to or from California around the date of your flight and the presence it kept here. Those things change, so it is worth checking against your actual itinerary rather than assuming in either direction, and it is worth doing early. Send us the itinerary and we can tell you where the claim can be brought. We go through how the forum works in suing a foreign airline in California.

Ownership, and Why It Gets Checked First

One question is worth settling at the start of any claim against a foreign carrier, because it changes the machinery of the case rather than its merits.

Under US law, an airline that 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 instead of a jury and the airline has to be served through a particular route rather than ordinary means. Several large international airlines are in that position and several are not, the holdings shift, and a government stake sometimes sits in a parent company rather than in the airline itself. It takes very little time to answer against a current source, and because it governs service of process, answering it late costs months.

Who You Actually Contracted With

Copa is a Star Alliance member with a close commercial relationship with its large US partner, so a meaningful share of its California traffic is sold under the American carrier's name and flight number. The treaty separates the contracting carrier that sold the ticket from the actual carrier that operated the flight and lets a claim proceed against either.

That is worth checking first, because a US carrier can be sued here without any foreign forum argument, which neatly sidesteps the whole analysis above. Look for the operated-by line on your booking confirmation. The boarding pass will not tell you.

What injures passengers

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

Six to seven hours is long enough for a full service cycle but well short of the ultra long haul routes.

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

Carts and hot drinks during a full service cycle. Six hours is long enough for the cabin to be worked more than once.

Turbulence

An unbelted passenger thrown from a seat. Turbulence over the tropics is a real and seasonal risk on these routings.

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 Tocumen is a premises claim in Panama, often on a much shorter deadline. Do not let it sit.

What the Short Sector Removes

Clots and the other duration problems barely arise, which takes away the most common reason one of these claims is denied.

Where We Are Not the Right Call

If you do not live in California, the residence forum follows your home, and on this carrier that is a serious problem rather than an inconvenience, because without the residence forum a Copa itinerary usually points to Panama or to a South American destination. If you were hurt inside the Panama City terminal during your connection rather than on the aircraft, the ramp, or the stairs, that is a Panamanian premises claim. If two years have gone by since the landing date, the claim is very probably over. And a baggage loss is a form in the airline's own process, filed inside a window counted in days.

What to Do This Week

One. Pull the booking confirmation and check whether the US partner or Copa sold you the ticket. If it was the partner, the forum analysis on this page becomes unnecessary.

Two. Confirm where you were living on the date of the flight, because on a Copa itinerary that fact is doing most of the work.

Three. Write down the sequence, with the external event at the center.

Four. See a physician now, and count two years from the landing date.

If you live in California and something external injured you on the aircraft, the residence forum ordinarily brings the case here even though every other signpost points to Panama. We evaluate these claims at no cost, and we will tell you plainly when the treaty's accident standard is not met.
