How to escalate an unresolved LATAM compensation claim

External escalation is most effective after coverage, operator, final arrival and cause have been audited. An authority cannot turn an ineligible inbound LATAM service into a European fixed-sum case.

Choose the route by function

Do not describe every government webform as a compensation tribunal. Read its current remit, admissibility requirements, language, deadline and legal effect.

Stage 1: finish a usable LATAM complaint

LATAM's Help Center provides a “Create a case” route and a case-status function. External reviewers generally expect proof that the passenger first complained to the airline. Preserve:

• case number and filing date;
• exact submitted text;
• original itinerary and operating-carrier evidence;
• final arrival or cancellation notice;
• amount per passenger and expense schedule;
• LATAM's full response;
• any focused follow-up and later answer.

If the first claim merely said “my flight was late,” repair it before escalation. The LATAM claim-form guide gives the eight factual steps. If LATAM used an unsupported exception, apply the rejection audit.

Stage 2: confirm that EU261 or UK261 applies

For LATAM, territorial scope is unusually important because it is a non-EU and non-UK group. A LATAM flight departing Madrid, Paris, Frankfurt, Lisbon or another protected European airport can use EU261. A Heathrow departure can use UK261. A LATAM-operated return from Sao Paulo, Santiago or Lima normally cannot use those regimes.

An external body will reject a case outside its remit even if the delay was severe. If an EU or UK partner actually operated the inbound flight, attach the “operated by” proof and direct the underlying compensation claim to that carrier.

Separate bookings can also change jurisdiction and final destination. State the ticket structure candidly.

EU departure: national enforcement is state-specific

The European Commission publishes a current list of national enforcement bodies. As a practical starting point, use the country where the incident occurred, often the departure state for a LATAM outbound flight. The body may investigate airline compliance and issue guidance, sanctions or decisions according to national law.

Some examples illustrate why one generic instruction is unsafe:

• Spain's AESA has an alternative dispute-resolution procedure for qualifying incidents and requires a prior airline claim;
• France distinguishes DGAC supervision from an individual mediation and court path;
• Germany separates LBA enforcement issues from consumer conciliation and judicial recovery;
• Italy, Portugal and other states maintain their own procedures and admissibility rules.

Open the live official page on the escalation date. Do not send a French-departure claim to AESA simply because LATAM's journey connects through Madrid later.

Spain and AESA

For a LATAM journey departing Spain, complain to LATAM first. AESA's current ADR information distinguishes incidents from 2 June 2023 onward and describes a prior-complaint requirement. Its current FAQ states that the airline should have at least one month to respond before the passenger proceeds, and identifies procedural time limits.

Attach the complete Spanish-origin booking, identity document requested by AESA, prior complaint, LATAM response, ticket and receipts. AESA accepts documents in Spanish or English according to its current guidance. Verify the exact electronic or non-electronic filing requirements.

AESA's scope does not follow LATAM around the world. A Sao Paulo-Madrid flight operated by LATAM ordinarily fails EU261 even though Spain is the destination. Do not use the destination alone to manufacture AESA jurisdiction.

France, Germany, Italy and Portugal

For France-origin disputes, DGAC reporting supports regulatory oversight, while individual recovery can require the correct mediator and, since the 2026 procedural change, mediation before many court claims. Verify LATAM's current mediator affiliation and transitional exceptions rather than naming an unavailable scheme.

German passengers should distinguish Schlichtung Reise & Verkehr or the competent consumer route from LBA supervision. Italian and Portuguese departures have their own authority and ADR architecture. The passenger's residence may affect consumer assistance, but the flight's territorial nexus remains central.

These routes evolve. Save the official eligibility page used on the filing date and meet its formatting and language rules.

UK departure: ADR or CAA PACT

Current UK CAA guidance says passengers should first complain to the airline. If dissatisfied with the final response, or if the airline takes more than eight weeks, the case can move to an approved ADR provider where the airline participates or potentially to the CAA's Passenger Advice and Complaints Team where it does not.

Check the current CAA airline/ADR listing before asserting that LATAM belongs to a named scheme. The CAA states that PACT may advise and take up a valid complaint but does not have legal power to impose a solution on an airline. That limitation should be understood before the passenger expects a binding award.

For a Heathrow-origin case, attach UK departure evidence, amount in pounds, final arrival, LATAM case history and receipts. A LATAM-operated inbound flight from South America normally is not covered merely because Heathrow is the destination.

The LATAM UK261 guide supplies the coverage and amount table.

Flights beginning in Latin America

A rejected Sao Paulo-Madrid, Santiago-Paris or Lima-London claim should not be escalated to an EU or UK body as if LATAM were a European carrier. Determine the operating affiliate and departure-country regime.

Possible channels include aviation and consumer authorities in Brazil, Chile, Peru, Colombia or another origin state, plus contractual complaint and court options. Remedies vary. Some systems emphasise re-accommodation, assistance, refund or proven damage rather than a fixed European tariff.

Use official local sources and state the actual remedy sought. The Montreal Convention can govern certain baggage and international-carriage damages, but it is not a substitute automatic delay tariff.

ADR, enforcement and court are not interchangeable

A national enforcement body can identify non-compliance without collecting money for an individual. ADR can produce a recommendation or binding result depending on its legal design. Mediation seeks settlement and may be a prerequisite to court. A court can issue an enforceable judgment but requires jurisdiction, service, evidence, fees and limitation analysis.

Before choosing, compare:

1. admissibility and prior-complaint waiting period;
2. whether LATAM participates or is bound;
3. maximum age of the incident;
4. accepted languages and document format;
5. whether parallel proceedings are prohibited;
6. cost and risk;
7. enforcement of the outcome.

Do not open overlapping proceedings that make each other inadmissible. Read the live rules first.

Jurisdiction and limitation

EU261 does not create one universal court limitation period. National limitation rules and jurisdictional links can control. A covered departure can provide a useful forum, while connection and contracting facts can add complexity.

UK court claims have their own procedure and limitation analysis. Latin American local claims follow their relevant national laws. LATAM's internal case remaining open does not necessarily suspend every external deadline.

The EU reform adopted in 2026 introduces a future harmonised notification period and airline response rule, but those provisions should not be treated as already applicable to all incidents on 25 August 2026. File promptly under current law.

Build an escalation packet

Use a one-page cover chronology followed by numbered exhibits:

1. passenger and contact details;
2. complete itinerary and operator;
3. legal coverage sentence;
4. disruption and final timing;
5. cause alleged by LATAM and your evidence-based response;
6. calculation per passenger;
7. care or replacement costs;
8. LATAM case and response;
9. exact requested outcome.

Translate only where the receiving procedure requires it. Keep original documents and explain currencies. A reviewer should be able to reconstruct the case without opening twenty unrelated screenshots.

Escalation examples

Madrid departure. LATAM rejects EUR 600 for two passengers after a controllable five-hour final delay. The passengers preserve the prior case and use AESA's current Spanish-departure ADR route when admissible. Their packet claims EUR 1,200 and separate receipts.

Heathrow departure. LATAM denies GBP 520 based on “technical circumstances.” After a final response, the passenger checks whether LATAM is signed to approved ADR; if not, current CAA guidance may make PACT available. The ordinary nature of the defect is supported with the airline's own message.

Sao Paulo departure. A LATAM-operated flight to Frankfurt is delayed six hours. EU261 escalation in Germany is normally the wrong route because the non-EU carrier journey began abroad. The passenger evaluates Brazilian rights, LATAM's contract and proved losses.

Partner-operated inbound. LATAM sells Lima-Madrid but Iberia operates and cancels it. The fixed-compensation complaint should normally go to Iberia, with appropriate EU redress if unresolved, rather than escalating a LATAM seller complaint to the wrong body.

FAQ

Which authority handles every LATAM compensation claim?

There is no single global authority. The covered departure, operating carrier, applicable regime and remedy determine the route.

Can I complain to AESA because my LATAM flight landed in Madrid?

Destination alone is insufficient. A LATAM-operated journey beginning outside the EU normally falls outside EU261; verify AESA's current territorial remit.

How long should I wait before UK escalation?

CAA guidance generally refers to an airline final response or more than eight weeks without one before ADR or PACT review.

Does PACT order LATAM to pay?

The CAA says PACT can advise and take up a complaint but lacks legal power to impose a solution. Check whether an approved ADR route applies.

Is the future nine-month EU deadline already active?

It should not be presented as universally active on 25 August 2026. Follow current national and court deadlines until the reform applies.
