In 2026, you don't "link" your Virgin Atlantic Flying Club and Delta SkyMiles accounts into a single pool of points; instead, you link your loyalty number to a specific reservation. Because they are joint-venture partners, you can earn Delta miles when flying Virgin, or vice versa. To do this, when booking a flight on either website, look for the "Loyalty Program" or "Frequent Flyer" dropdown menu and select the program you wish to credit. If you have already booked, you can go to "Manage My Booking" on either airline's app and enter your partner loyalty number there. This ensures that your Elite Status benefits (like lounge access or extra baggage) are recognized across both airlines. Furthermore, if you are using points, you can book Delta flights directly on the Virgin Atlantic website (and vice versa) by selecting the "Pay with Points" option. In 2026, the systems are highly integrated, so entering your number once usually "syncs" the record across both carriers' manifests within minutes.
