I'm trying to finalize my travel plans. I would like to utilize the amex (sweden) 2-4-1 companion voucher that I have, and ideally use it for an open jaw booking. Does anyone know if a booking like this is possible:
CPH-EWR, IAD-CPH?
Or would I be forced to either take
CPH-EWR-CPH or
CPH-IAD-CPH?

Unfortunately, I can't find the t&c anywhere, and searching the forums didn't help me find any answers.
