I actually had to do this recently, so I can walk you through it from personal experience. A few weeks ago, I booked a round-trip Delta flight for a family event, but plans changed — I only needed the return leg. I wasn’t sure if I could cancel just one part without losing the whole booking, so I called 877-297-0699, which turned out to be the easiest and fastest way to handle it.
The agent was super helpful and explained that Delta allows you to cancel one segment, but it has to be done manually so the rest of your trip isn’t affected. They confirmed my details, adjusted my itinerary, and even refunded the taxes for the canceled leg within a few days. The process took less than 15 minutes over the phone.
If you try doing it online, the system might ask you to cancel the entire ticket — so I definitely recommend calling 877-297-0699 directly. It saves time, avoids confusion, and ensures your remaining flight stays intact. Honestly, it’s the most reliable way to modify or cancel just one leg of your Delta flight without messing up the rest of your trip.
