To give feedback or file a complaint with Delta Air Lines using the company's website, go to its online Help Center and select the option for leaving comments and complaints. (Logging into your Delta SkyMiles account might speed the process along.)
Be sure to have your flight information, including confirmation number and flight number, available along with checked luggage info if applicable.
Filing general complaints to Delta Air Lines
To file a general complaint, which includes any issue other than one involving baggage claim, select "Submit Feedback" and follow the prompts to describe your issue. You'll be given a case number and a customer service rep should get back to you.
Later, you can check on the status of your complaint by going to the same page where you chose the feedback form and clicking "Check Feedback Case Status." You'll need to enter your last name and case number.
Filing baggage claim complaints to Delta Air Lines
To file a baggage claim for lost, damaged, or delayed luggage, you'll need to obtain a reference number from a Delta staff member at the airport when you first notify the airline of your issue. Use that to fill out a separate online form.
As with general feedback, you should be given a case number in order to keep track of the status of your complaint.
If you accidentally left an item on a plane, in a Delta lounge, or at a Delta gate, use the official Lost and Found page (https://app.nettracer.aero/lf-pax/delta/landing) to file a request to locate your item. You'll use the same page to track existing requests.
You can also message Delta directly by clicking the Message Us chatbot prompt on the Help Center website page or initiating the chat option by clicking the Delta logo at the top right of the Delta mobile app.
To speak with a Delta customer service rep by phone about a new or existing reservation, call 800/323-2323. Calls are accepted 24/7, but don't be surprised if your wait time to speak with someone is eternal.
Delta's phone number for baggage issues is 800/325-8224. That line is operated from 6am to midnight ET, 7 days a week.
To mail in a complaint (or—why not?—a compliment) after travel, send correspondence to this address:
Delta Air Lines, Inc.
Customer Care
P.O. Box 20980
Department 980
Atlanta, GA 30320-2980
Note that if you booked your flight through a third-party service, such as an online travel agency, you should contact that third party, not Delta, to make a change or cancellation.
Delta's social media accounts are not as responsive as the other contact methods listed. But if you decide to try, you'll go to the company's Facebook page or tag the carrier @Delta on Twitter.
If the company is unable to resolve your complaint to your satisfaction and you'd like to escalate the matter by filing a complaint against the airline with the U.S. government, follow our step-by-step instructions for doing that.
