How to Write a Demand Letter to an Airline

A demand letter is the most effective tool to get an airline to take your baggage claim seriously. It shows you know your rights, have documented everything, and are prepared to escalate. Here's how to write one that gets results.

When to Send a Demand Letter

Send a demand letter when:

The airline denied your claim and you've already appealed informally

The airline offered less than you're owed and won't negotiate

The airline hasn't responded within 30 days

You've filed a DOT complaint and want to reinforce your position

As a final step before small claims court

Key Elements of an Effective Demand Letter

1. Your Information and Claim Details

Your full name and address

PIR reference number

Claim/case number

Flight details (date, route, flight number, confirmation code)

2. Timeline of Events

When the incident occurred

When you reported it at the airport

When you filed the formal claim

Any correspondence with the airline (dates and summary)

3. Legal Basis

Domestic flights: Cite 14 CFR Part 254 and the $4,700 liability limit

International flights: Cite Montreal Convention Articles 17, 19, and 22 and the 1,519 SDR limit

EU flights: Also cite EU Regulation 889/2002 if applicable

Mention the airline's Contract of Carriage obligations

4. Specific Demand

State the exact dollar amount you're claiming

Break it down: bag value + contents + interim expenses

Reference your itemized list of contents

5. Deadline and Consequences

Give the airline 14-30 days to respond

State that you will file in small claims court if the demand is not met

Mention that you have already filed (or will file) a DOT complaint

Template Structure

Here's the structure your demand letter should follow:

[Your Name] [Your Address] [Date]

[Airline Name] [Claims Department Address]

Re: Baggage Claim — [PIR Number] — [Flight Number] — [Date of Travel]

Dear [Airline] Claims Department,

Paragraph 1: I am writing regarding my unresolved baggage claim. On [date], I traveled on [flight]. My checked baggage was [lost/damaged/delayed]. I filed a PIR at [airport] (reference: [number]).

Paragraph 2: On [date], I submitted a formal claim for $[amount]. The claim included [describe documentation]. Despite [X days/months], this claim remains unresolved / was denied for [reason] / was undervalued at $[amount offered].

Paragraph 3: Under [14 CFR Part 254 / Montreal Convention Article 22], [airline] is liable for up to [$4,700 / 1,519 SDR] per passenger. My documented losses total $[amount], which falls within these limits.

Paragraph 4: I hereby demand payment of $[specific amount] within 30 days of this letter. If this matter is not resolved by [specific date], I will pursue all available remedies, including filing a complaint with the US Department of Transportation and initiating action in small claims court.

Sincerely, [Your Name]

Enclosures: Itemized loss list, receipts, PIR copy, previous correspondence

Pro Tips

Send via certified mail AND email — certified mail shows you're serious and provides proof of delivery

Be factual, not emotional — stick to dates, amounts, and regulations

Attach all evidence — don't make the airline request it

Copy the DOT — add "CC: US DOT Aviation Consumer Protection Division" at the bottom

Keep a copy for your records and potential court filing

Know the compensation limits before citing them in your letter

What Happens After Sending

Best case: The airline settles within 2-4 weeks

Common case: The airline makes a counteroffer — negotiate from there

Worst case: No response — you now have documentation to file in small claims court

Most airlines take demand letters seriously because they know the next step is legal action, and losing in small claims court is both costly (judgment + court costs) and creates a record.

Frequently Asked Questions

Do I need a lawyer to write a demand letter?

No. Demand letters for baggage claims are straightforward enough to write yourself. The key is citing the correct regulation and being specific about your claim amount.

What if the airline responds with a lower offer?

Counter-offer. You're now negotiating. Reference your documentation and the regulation. If they won't budge, proceed to small claims court with your demand letter as evidence.

Can I send a demand letter before filing a DOT complaint?

Yes, you can send them in either order. Some people prefer to file the DOT complaint first (so they can reference it in the demand letter), while others send the demand letter first and use the DOT complaint as an escalation if the letter doesn't work.

Where to Send Your Demand Letter: Airline Contact Addresses

A demand letter needs to reach the right department. Here are the claims department addresses for major airlines — sending to the wrong department can add weeks to your timeline.

US Carriers

American Airlines: Send to the Customer Relations department. American accepts demand letters via both email and certified mail. Check our American Airlines page for the current claims address.

Delta Air Lines: Delta's claims correspondence should go to their Customer Care team. They accept letters at their Atlanta headquarters. See our Delta page for exact contact details.

United Airlines: Address your demand letter to United's Customer Care division. They accept both email and postal correspondence. Visit our United page for current addresses.

Southwest Airlines: Southwest's Customer Relations department handles escalated claims. They're based in Dallas. Our Southwest page has the specific mailing address.

Spirit Airlines: Spirit's Guest Relations handles demand letters. Given Spirit's more rigid claims process, a well-documented demand letter can be especially effective.

For international airlines, send your demand letter to their US office (if they have one) or to their headquarters:
