Demand Letter to Airline: Get Compensated for Delays, Lost Bags, and Bumped Flights

Your flight was cancelled. Or delayed 8 hours. Or they lost your luggage. Or they bumped you from an overbooked flight and stuck you on a red-eye the next day. Now the airline is offering you a $50 voucher like that fixes everything.

Airlines count on passengers not knowing their rights. A demand letter shows you do. Here's how to write one that gets you real compensation, not airline funny money.

Your Rights as an Airline Passenger

The U.S. Department of Transportation (DOT) has specific rules about what airlines owe you. These aren't suggestions. They're federal regulations.

Involuntary Bumping (Denied Boarding)

If the airline overbooked and bumped you against your will, you're entitled to cash compensation. Not a voucher. Cash. The amount depends on how long you're delayed:

Delay	Domestic Flights	International Flights
1-2 hours (domestic) / 1-4 hours (international)	200% of one-way fare (max $775)	200% of one-way fare (max $775)
Over 2 hours (domestic) / Over 4 hours (international)	400% of one-way fare (max $1,550)	400% of one-way fare (max $1,550)
Arrives within 1 hour of original time	No compensation required	No compensation required

Important: This applies to involuntary bumping only. If you voluntarily gave up your seat for a voucher, you accepted those terms. But if you said no and they bumped you anyway, you're owed cash.

Flight Cancellations and Significant Delays

Under DOT rules effective since 2024:

• Airlines must provide automatic cash refunds for cancelled flights
• Significant delays (3+ hours domestic, 6+ hours international) trigger refund rights
• Refunds must be issued within 7 business days (credit card) or 20 business days (other payment)
• Airlines cannot substitute vouchers or credits unless you specifically choose them

Lost, Delayed, or Damaged Luggage

• Domestic flights: Airlines are liable up to $3,800 per passenger for lost, delayed, or damaged bags
• International flights: Liability is approximately $1,780 per passenger under the Montreal Convention
• Airlines must reimburse reasonable expenses if your bag is delayed (toiletries, clothing, etc.)
• You must file a claim within specific timeframes (typically 21 days for international, varies for domestic)

Tarmac Delays

• Airlines cannot keep you on the tarmac for more than 3 hours (domestic) or 4 hours (international) without letting you deplane
• Food, water, and working lavatories must be provided within 2 hours
• Violations can result in fines of up to $27,500 per passenger

How Much You're Owed

Calculate Your Total Claim

Your demand should include everything the airline owes you:

Category	What to Claim	Documentation
Ticket refund	Full fare paid (if flight cancelled or significantly delayed)	Booking confirmation, credit card statement
Bumping compensation	200-400% of one-way fare	Boarding pass, denial notice
Hotel costs	Actual cost of overnight stay due to delay	Hotel receipt
Meals	Reasonable meal costs during delay	Restaurant receipts

4. Itemized damages: every cost with documentation

Airline Demand Letter Template

Filing a DOT Complaint

The Department of Transportation takes airline complaints seriously. Here's how to file:

How to File

1. Go to airconsumer.dot.gov
2. Select "File a Consumer Complaint"
3. Choose the complaint category (flight problem, baggage, bumping, etc.)
4. Provide flight details and describe what happened
5. Attach your demand letter and documentation

Why It Works

• DOT forwards complaints directly to the airline, which must respond
• Airlines track complaint volumes. High numbers trigger DOT investigations.
• DOT can fine airlines up to $27,500 per violation
• Complaint data is published in monthly Air Travel Consumer Reports, which airlines hate

Credit Card Chargebacks

If the airline won't refund a cancelled flight, file a chargeback with your credit card company. Under the Fair Credit Billing Act, you can dispute charges for services not rendered. This is separate from your demand letter and puts additional pressure on the airline.

EU Flights: Additional Rights Under EC 261

If your flight departed from an EU airport (any airline) or arrived at an EU airport (EU airline), you have additional rights under EC 261/2004:

Flight Distance	Delay Over 3 Hours	Compensation
Under 1,500 km	3+ hours	€250 ($270)
1,500-3,500 km	3+ hours	€400 ($435)
Over 3,500 km	4+ hours	€600 ($650)

This compensation is in addition to any refund, rebooking, or expense reimbursement. The airline must pay even if they rebooked you on another flight, as long as you arrived 3+ hours late.

Exception: Airlines don't have to pay if the disruption was caused by "extraordinary circumstances" (severe weather, air traffic control strikes, security threats). But mechanical issues and crew shortages are NOT extraordinary circumstances, so airlines can't use those as excuses.

If the Airline Won't Pay

Small Claims Court

Airlines lose small claims cases all the time because they often don't send a representative to court. Your case is strongest when you have:

• Clear documentation of the disruption
• Receipts for all out-of-pocket expenses
• Your demand letter showing you tried to resolve it
• The specific DOT regulation they violated

Credit Card Dispute

For cancelled flights, your credit card company can reverse the charge. This is often the fastest path to getting your money back. File within 60 days of the statement date.

Third-Party Claim Services

For EU flights, companies like AirHelp and Flightright will pursue your EC 261 claim on a no-win, no-fee basis (typically taking 25-35% of the compensation). Worth considering if the airline is being difficult and you don't want to deal with the hassle.

Social Media Pressure

Airlines have dedicated social media teams that often resolve issues faster than phone support. A factual, public tweet or post about your experience (with your case number) can get attention quickly. But always pursue formal channels first.
