As of a couple hours ago, the fare itself was still around but had gone up to around $2,100, which is still a very solid deal for ORD-CPT. The main challenge is finding P availability, which is extremely limited.
Seems like OS has just added 3x weekly VIE-CPT into the schedule for the northern hemisphere fall/winter. I've been able to find some P on that, e.g., ORD-LHR-VIE-CPT, but the layovers can be long. Others have found P on double connections within the US, e.g., ORD-DCA-EWR-CPT.
