Alaska still flies a 73G to ORD every day, but they have changed the schedule. Flight 130 now arrives at ORD at 5:01 PM, and flight 131 leaves ORD at 6:00 PM. Until this October, the ANC-ORD segment was a red-eye.
This is all very tentative, but Alaska's schedules currently show an additional ANC-ORD non-stop in the works for next summer. So, if all goes as planned, the original flight will be back, as well as the current nonstop.
