How to File a Complaint with an Airline (and Actually Get a Response)
Whether it’s a delayed flight, lost baggage, rude service, or a denied refund, dealing with airline issues can be frustrating. But instead of letting your complaint go unheard, you can take specific steps to file it effectively—and increase your chances of getting a meaningful response. This guide walks you through exactly how to file a complaint with an airline, what to include, and how to escalate the issue if necessary.
When Should You File a Complaint?
You should consider filing a formal complaint if you’ve experienced:
- A flight delay or cancellation without adequate support
- Lost or damaged luggage
- Denied boarding or overbooking
- Poor customer service
- Refund denial
- Unexpected charges or billing errors
Complaints can lead to:
- Refunds or vouchers
- Apologies and policy changes
- Travel credit or compensation
Step-by-Step: How to File a Complaint with an Airline
1. Gather All Relevant Details
Before submitting your complaint, gather:
- Flight number, route, and date
- Booking confirmation or ticket number
- Baggage claim numbers (if relevant)
- Receipts for out-of-pocket expenses
- Names of employees (if available)
- Screenshots, photos, or emails related to the issue
2. Contact the Airline Directly
Start with the airline’s official customer service channels:
- Visit their website and find the “Contact Us” or “Customer Relations” page
- Submit a complaint via the online form or email address
- Use the chat support feature or customer service phone number if urgent
Each airline has a complaint form, such as:
- American Airlines: https://www.aa.com/contact/forms
- Delta Air Lines: https://www.delta.com/contactus
- United Airlines: https://www.united.com/en/us/customercare
- Southwest Airlines: https://support.southwest.com
- JetBlue: https://www.jetblue.com/contact-us
Be polite, concise, and factual. Stick to the who, what, where, and when.

3. Include These Key Elements in Your Complaint
To increase the likelihood of a response:
- Subject Line: Clear and specific (e.g., “Delayed Flight – Request for Compensation, Flight #AA123 on May 5”)
- Introduction: State the problem quickly
- Details: What happened, when, and how it affected you
- Resolution: What you’re requesting (e.g., refund, compensation, apology)
- Attachments: Upload receipts, photos, and boarding passes
4. Follow Up in 7–10 Days
If you don’t hear back within a week:
- Reply to the original email or reference your case number
- Keep communication professional and polite
- Consider reaching out through social media, as many airlines prioritize public-facing platforms like Twitter/X and Facebook for urgent responses
How to Escalate Your Complaint
If the airline ignores your issue or doesn’t offer a fair resolution, escalate the complaint using one of the following options:
1. U.S. Department of Transportation (DOT)
For flights involving U.S. carriers or airports, file a complaint here:
The DOT forwards the complaint to the airline and requires a written response. They also track complaints to hold airlines accountable.
2. European Union Authorities (EU261)
If your flight departed from the EU or you flew with an EU airline:
- Contact the airline first, then
- File with the National Enforcement Body (NEB) of the EU country
- You may also qualify for €250–€600 compensation under EU261
3. Canadian Transportation Agency (CTA)
If flying within or to/from Canada:
- Submit a complaint to: https://rpa-apr.ca/complaints
Canada’s Air Passenger Protection Regulations (APPR) entitle travelers to compensation for delays, cancellations, and poor treatment.
4. File a Credit Card Dispute
If your complaint involves non-delivery of service or denied refunds, you can:
- Contact your credit card issuer to initiate a chargeback
- Provide proof of service failure or refund refusal
This is especially useful if you never received a promised service (like baggage delivery or a confirmed refund).
5. Use a Third-Party Claim Service
For complex complaints or denied compensation, companies like:
- AirHelp
- ClaimCompass
- Compensair
…can handle your claim for a fee or percentage of the compensation.
Bonus Tip: Use Social Media Strategically
Airlines often monitor platforms like Twitter/X and Facebook more closely than email. When posting:
- Be polite and factual
- Include your confirmation number (privately if possible)
- Tag the airline and keep your message public for visibility

Frequently Asked Questions (FAQs)
How long does it take for airlines to respond to complaints?
Responses typically take 7–30 days, depending on the airline and issue severity.
What should I do if the airline refuses to help?
Escalate to a consumer protection agency like the DOT, EU NEB, or CTA, or pursue a credit card chargeback.
Is social media really effective?
Yes—many airlines respond faster to public tweets or Facebook posts than private emails.
Will I always receive compensation?
Not always. It depends on the airline’s policies and the cause of your issue. Delays due to weather, for example, may not be compensated.
