When using travelling by air, it’s essential to be aware of your rights as a passenger and the available channels for addressing airline complaints or seeking resolution. Delta Air Lines, commonly known as Delta, is a prominent airline operating many flights daily. While striving to deliver exceptional service, the airline acknowledges occasional issues may arise during your journey.

What Can You Make a Complaint About

As a passenger, you have the option to file a complaint with Delta regarding various issues that may have arisen during your travel experience. Here are common reasons passengers file complaints with Delta Air Lines:

• A Delayed or Cancelled Flight: If your Delta flight experiences significant delays or is cancelled, you can file an official complaint to express your dissatisfaction and, in some instances, seek Delta delayed or cancelled flight compensation for the inconvenience. Your eligibility for flight delay compensation or cancelled flight compensation depends on where your Delta flight departs from.
• Denied Boarding: If you face boarding denial due to overbooking, you can file a complaint with Delta Air Lines to address the situation and request a full flight ticket refund in addition to monetary compensation, irrespective of your country of departure.
• A Baggage Issue: If, when flying on Delta, your luggage is lost, damaged, or delayed, you have the right to file a complaint and request reimbursement for any expenses incurred as a result.
• A Customer Service Concern: If you’ve encountered poor customer service from Delta Air Lines, you can submit a complaint to address the issue and provide feedback regarding your experience.
• Inadequate Compensation: If you believe the compensation offered by Delta for a flight disruption or other inconvenience you experienced is insufficient, you can file a complaint to request a reassessment of the compensation provided.
• An Accessibility Concern: If you’ve encountered challenges or received insufficient assistance related to accessibility, you can file a complaint with Delta Air Lines to draw attention to the issue and prompt the airline to take necessary measures to improve accessibility.
• Billing Disputes: If you have any concerns regarding refunds, overcharges, or billing disputes with Delta Air Lines, filing a complaint can initiate an investigation by the airline. 

If you face a scenario with Delta that compels you to complain, retaining any supporting documentation can help bolster your complaint and compensation claim, if you make one. Supporting documentation can include boarding passes, receipts, or any correspondence with the airline.

Know Your Passenger Rights

When travelling on Delta on flights originating from or within the United States, your travel rights are principally dictated by US laws. Conversely, if your Delta flight leaves from a country within the European Union (EU), you might be eligible for protection under EU Regulation 261 from 2004. Discover the basics of your passenger rights in both the US and EU below:

United States

In the US, passenger rights are overseen by the US Department of Transportation (DOT). The DOT has established guidelines and rules to protect you in the case of a variety of flight disruptions, including delays and cancellations, boarding denials due to overbooked flight, luggage complications, and more.

These rules guarantee certain privileges and options for remediation, should there be interruptions or difficulties during your travel from or within the US. However, these rarely involve financial reimbursement.

Europe

In Europe, EU261 safeguards your travel rights of passengers. This regulation protects you in situations like flight delays, cancellations, denied boarding, and luggage issues.

The law provides various privileges and options, including financial compensation. The compensation amount is determined by the flight's distance and the duration of the delay or cancellation. If you qualify for financial compensation under EU261, the amount may range from $280 to $670.

How to Make a Complaint to Delta

A good first step can be to initiate contact with the Delta customer service team and present your case, ensuring you include any corroborative materials that support your claim. Be sure to articulate clearly what you would consider to be a fair resolution, but ensure your demands are within reason.

It’s essential to keep track of all correspondence and dealings you have with Delta Air Lines throughout the process and follow up on your complaint, and even elevate the matter within the organization as necessary.

Should you find the process overwhelming or feel that your rights as a passenger are not being adequately represented, it might be beneficial to seek help from a third-party organization. For instance, our expert team at AirAdvisor is here to champion your passenger rights on your behalf.
