Delta Air Lines

In short

File written complaints through Delta's Comment & Complaint form; Delta says it acknowledges within 30 days and answers within 60. Refunds after a Delta cancellation or significant change go through the refund form, and meal or hotel costs from a delay Delta caused go through the reimbursement form. Report bag damage within 6 hours on domestic tickets issued since October 8, 2025. Delta's contract gives only one year to start a lawsuit.

How complaints actually go

• Delta's Customer Service Plan names the Comment & Complaint form as the way to file a written complaint, and says Delta acknowledges written complaints within 30 days and sends a substantive response within 60 days. Delta: customer commitment
• Delta says that if you decline rebooking after a cancellation or significant change, you can get a refund of the unflown portion plus prepaid seat and bag fees, or a 5-year eCredit. If Delta cannot rebook you and you take no action within 24 hours, Delta refunds. Delta: cancel a flight
• The meal and hotel reimbursement form is limited to U.S. and Canada residents; others use the Comment & Complaint form. Delta: cancel a flight
• DOT opened an investigation of Delta's handling of the July 2024 CrowdStrike outage and later closed it without a penalty. A DOT spokesperson said in June 2026 that passengers received prompt refunds and baggage help, and that Delta was directed to give timely notice of the right to seek a refund. Passenger class actions were still pending. Atlanta News First via WALB, June 16, 2026

What tends to work

• For a delay or cancellation within Delta's control, the Customer Service Plan promises a meal or meal voucher at 3 or more hours, a hotel (based on availability) and ground transportation if you are stuck overnight away from home, and says representatives may offer gift cards, travel credits or miles. Ask for these and keep receipts. Delta: customer commitment
• Delta refunds the checked bag fee if a domestic bag is not delivered within 12 hours of arrival at the gate (15 or 30 hours on international flights). Delta: delayed, lost or damaged baggage
• Delta defines a significant schedule change as 3 or more hours earlier or later (domestic) or 6 hours (international); cite this when you ask for a refund instead of rebooking (rule dot-refunds-rule). Delta: cancel a flight
• If Delta does not resolve the complaint, DOT directs it to respond to you directly and to send DOT a copy. DOT: File a consumer complaint

Traps and fine print

• Delta's Contract of Carriage says any legal action must start within one year after the event. Delta Contract of Carriage
• An eCredit from cancelling a nonrefundable ticket yourself expires 1 year from the purchase date unless the ticket terms say otherwise. Basic Economy cannot be changed or refunded after the risk-free cancellation period. Delta: cancel a flight

Scams that target customers
