Yes, a Delta Companion Certificate (earned via certain American Express cards) can be gifted, but with a major catch: the person who uses the certificate does not have to be the cardholder, but the primary ticket must be purchased using the cardholder's SkyMiles account. In 2026, you can book a flight for two people—say, your brother and his wife—using your certificate, but you must be the one to log in and initiate the booking. Once the tickets are issued, they are tied to those specific names and cannot be changed. Crucially, the "Companion" must travel on the exact same itinerary and in the same cabin as the primary traveler. While you can gift the "trip" to others, the certificate itself cannot be "transferred" into someone else's digital wallet for them to use at their own discretion later. This ensures that the cardmember retains control over the high-value perk while still allowing them to treat friends or family to a "buy-one-get-one-free" flight experience.
