Timeline: You can file a complaint with the DOT at any time after attempting to resolve the issue with Delta Air Lines directly. The DOT will process and serve your complaint to the airline, holding them to strict federal response timelines.
Level 4: Legal Action (Final Step)
- Pre-Litigation: Before pursuing legal action, carefully review the Delta Air Lines Contract of Carriage. Delta does not mandate binding arbitration for standard flight/passenger disputes; however, they strictly enforce a Class Action Waiver, meaning you must sue the airline in your individual capacity, not as part of a class.
- Court: If the regulatory and corporate routes fail, you may file a lawsuit in Small Claims Court for claims below your state’s limit (e.g., up to $15,000 in Georgia). Ensure you bring all documentation, DOT complaint records, and baggage/ticket receipts.
