Step-by-Step: Suing an Airline in Washington
Confirm your claim is within Washington's $10,000 limit
Washington's small claims limit is $10,000. If your damages are higher, you can reduce your claim to the limit or file in Washington civil court. Use our Washington Small Claims Limit guide for the full details.
Send a demand letter first
File a DOT complaint at airconsumer.dot.gov first — this creates a federal record and sometimes generates a resolution. If not, your DOT case number strengthens your small claims filing. Courts in Washington expect plaintiffs to have made a good-faith attempt to resolve the dispute. A demand letter also creates a paper trail and often prompts payment without any court filing.
Gather your evidence
Your case is only as strong as your evidence. Collect everything before filing — see the checklist below for exactly what you need for a airline dispute.
Find the right Washington courthouse
File at the Small Claims Department in the Washington county where the airline is located, does business, or where the dispute occurred. Before filing, look up the airline's correct legal name and registered agent on the Washington Secretary of State →. Using the wrong legal name is a common reason cases are dismissed.
Pay the filing fee ($31–$50)
Washington small claims filing fees range from $31 to $50 depending on your claim amount. Use our Washington Filing Fee Calculator to find the exact amount for your claim. Keep your file-stamped copy.
Serve the defendant properly
The airline must be formally notified of the lawsuit. Washington courts provide specific instructions — follow them exactly. Improper service is one of the most common reasons cases are dismissed.
Present your case at the hearing
Bring 3 organized copies of all evidence. Present your case in order: what happened, how much you lost, and why the airline is responsible. Most Washington small claims hearings last 15–30 minutes. Stay calm, stick to facts, and let the judge ask questions.
Sample Demand Letter: Airline Dispute
Send this demand letter via certified mail before filing. Courts view prior good-faith attempts favorably, and many disputes settle at this stage. Replace the bracketed placeholders with your details.
I am writing to demand $[AMOUNT] in compensation from [DEFENDANT NAME] for [INCIDENT DESCRIPTION] on [DATE], which caused me significant financial harm and inconvenience. As [PLAINTIFF NAME], I am entitled to reimbursement under federal regulations, your published customer service commitments, or general contract law for costs including but not limited to replacement transportation, lodging, and the value of lost or delayed baggage. Despite submitting a formal claim to your customer service department, I have not received adequate compensation. If you do not resolve this matter with full payment within 14 days, I will file a claim against you in small claims court for the full amount plus any applicable filing costs.
This is a template only — not legal advice. Consult an attorney if your situation is complex or the amount is significant.

Tips for Winning Your Airline Case in Washington
File in the small claims court in your county — not near the airline's headquarters. Airlines are registered to do business in every state and must respond locally.
Under DOT rules, airlines must provide cash refunds (not vouchers) for canceled flights if you choose not to travel. This is a strong basis for suit.
Airlines often default or settle small claims rather than send an attorney, especially for amounts under $1,000.
If bumped involuntarily, DOT rules require airlines to pay 200–400% of your one-way fare in compensation. Document your boarding denial in writing immediately.
