Dear Customer,
Due to a system error with a mistaken fare, your Delta ticket for travel on Air France in La Première/First Class which was recently purchased has to be cancelled.
You will be rebooked in Business Class for the same date and flight; alternatively, you may request a full refund of the fare paid, consistent with DOT guidelines and policy.
We apologize for this inconvenience. If you have any questions in the meantime, you may Contact Us on Delta.com to help you in this matter.
Kind Regards,
Air France
