The grapevine says DL only has a handful of domestics left they want to add. ORD/IAH/IAD/ABQ and RNO. BWI/OKC also wouldn't shock me. (ABQ/RNO/IAD/OKC/BWI would probably be 1-2x each at most. ORD/IAH are the only two that would get meaningful frequency) The new focus is going to be less about adding destinations and more about big planes and more frequency. ELP would likely go to SLC if it gets a flight out west. Internationally however there are plenty of places DL is looking at, but it will have to wait on A350s or used widebodies. They might be able to add something like a PEK or ICN flight with the available fleet but the international fleet is stretched pretty far.
