How to Complain to LATAM Airlines

LATAM Airlines is Latin America's largest airline group. Passengers most often complain about delays and cancellations with no compensation, refunds turned into vouchers, denied boarding, and lost or damaged baggage. A written complaint that cites the passenger-rights rules for your route — with a firm deadline — gets far better results than calling.

Quick answer

The most effective way to complain to LATAM Airlines is in writing — through its official complaint form or customer-relations email — stating what happened, the exact resolution you want, and a deadline to respond. Cite EU/UK Regulation 261/2004 (where applicable) and keep a copy. If LATAM Airlines ignores you, escalate to US Department of Transportation (DOT) or dispute the charge with your credit-card issuer.

Best way to contact LATAM Airlines

Official complaint form

Put your complaint in writing — it creates a record LATAM Airlines has to answer. Useful channels:

The airline's official website help centre or online complaint form
The airline app or live chat (keep screenshots of any promises)
Customer Relations by phone — note the agent name, date, and any case number
Postal mail to the airline's customer relations address (best for a paper trail)
A public post tagging the airline on X/Twitter or Facebook often speeds up a stalled case
The national aviation regulator if the airline ignores or rejects a valid claim

What to include in your complaint

The stronger your documentation, the harder it is for LATAM Airlines to dismiss your claim. Include:

Booking reference / PNR and ticket number

Flight number, route, and original vs. actual departure/arrival times

Boarding passes and any rebooking confirmations

Receipts for meals, hotels, transport, or replacement items during the disruption

Photos of damaged baggage and the property irregularity (PIR) report

A short timeline of events and the exact compensation or refund amount you're claiming

Step-by-step: how to complain to LATAM Airlines

Gather your evidence

Collect your booking or confirmation number, dates, the amount in dispute, receipts, photos or screenshots, and a short timeline of what went wrong. Strong documentation is what turns your airline complaint from "your word against theirs" into a claim they have to take seriously.

Send a written complaint

Submit a clear, dated complaint in writing through the airline's official complaint form or customer relations email. State what happened, the law or policy that applies, the exact resolution you want (refund, compensation, or reversal), and a reasonable deadline to respond. Keep a copy.

Give them a reasonable deadline

Allow a defined window — typically 14 to 30 days — for a written reply. A deadline in your letter creates a paper trail and removes the "we never received it" excuse.

Escalate internally

If you get no reply or a brush-off, escalate to the customer relations or executive office and reference your original complaint and deadline. Restate your requested resolution and note that you are prepared to take it further.

Escalate externally

Still unresolved? File with your national aviation regulator (e.g. the CTA in Canada, the DOT in the US, or the CAA/national authority in Europe), and consider a credit-card chargeback if you paid by card. These external routes are free and put real pressure on the company.

Common reasons people complain about LATAM Airlines

Flight delayed or cancelled without compensation
Refund refused for a cancelled flight
Lost, delayed, or damaged baggage
Denied boarding due to overbooking
Wrongful fees for seats, bags, or changes
Customer service ignoring the complaint

Your rights and possible remedies

Depending on your route, you may be entitled to fixed cash compensation for controllable delays and cancellations, a full refund when a flight is cancelled (cash, not just a voucher), care during long delays (meals and accommodation), and reimbursement for lost, delayed, or damaged baggage. Airlines routinely offer vouchers or deny valid claims first — a written demand citing the specific regulation is what gets cash paid.

Laws that may apply

· EU/UK Regulation 261/2004 (where applicable)
· Montreal Convention
· Local civil aviation regulations

When to escalate

Frequently asked questions

How do I complain to LATAM Airlines?

Put your complaint to LATAM Airlines in writing — through its official complaint form, customer-relations email, or a letter — rather than only by phone. State what happened, the resolution you want, and a deadline to respond. A written complaint citing EU/UK Regulation 261/2004 (where applicable) creates a record LATAM Airlines has to answer.

Can I get my money back from LATAM Airlines?

Often, yes. Under EU/UK Regulation 261/2004 (where applicable) you have rights when LATAM Airlines wrongly charges you or refuses a refund you're owed. A formal written request is your most effective tool; if LATAM Airlines refuses, you can escalate to US Department of Transportation (DOT) or dispute the charge with your credit-card issuer.

What should I do if LATAM Airlines ignores my complaint?

If LATAM Airlines misses your deadline or brushes you off, escalate in writing to its customer-relations or executive office, file a complaint with US Department of Transportation (DOT), and consider a credit-card chargeback or small claims court for the amount owed.

Can I ask LATAM Airlines for compensation?

Yes — where you've suffered a loss LATAM Airlines is responsible for, you can request compensation, a refund, or a credit. Be specific about the amount and attach evidence (receipts, photos, a timeline). Vague requests get vague answers; a precise, documented claim gets results.

Can I dispute a LATAM Airlines charge with my credit card?

If you paid by card and LATAM Airlines charged you for something you didn't authorize, didn't receive, or that wasn't as described, a chargeback through your card issuer is often the fastest route. Keep your written complaint and LATAM Airlines's response as evidence for the dispute.

How long does LATAM Airlines take to respond to a complaint?

Response times vary, but you should set your own reasonable deadline — typically 14 to 30 days — in your written complaint. If LATAM Airlines doesn't reply in that window, that itself becomes grounds to escalate to US Department of Transportation (DOT).
