How To Dispute Delta Airlines Double Charge For The Same Ticket?

If Delta double-charged you, call +1-833-770-4333 for immediate billing investigation. Duplicate charges often come from pending authorization holds, but calling +1-833-770-4333 confirms whether both charges fully posted. Check your bank statement for "pending" vs. "posted." Delta can reverse accidental double charges within a few days. If unresolved, file a chargeback with your bank and send Delta proof of duplicate billing.
