Global and Regional Upgrade Certificates are benefits available to Medallion elite members. They allow travelers to confirm upgrades into higher cabins like Delta One, First Class, or Comfort Plus, subject to availability. Certificates can be applied at booking or later via “My Trips.” They are valid for both domestic and international flights but must be used before expiration. Availability depends on route, demand, and fare type purchased. To apply certificates or confirm availability for your upcoming itinerary, call Delta Airlines reservations at 877-297-0699 and a representative can guide you.
