Human Factors; Procedure
This flight was a trip built by scheduling to operate a 767 into ZZZ that I picked up on open time as a 757/FO (First Officer). I have previously flown a 757 into ZZZ; but was not aware of a restriction to use this only as an alternate airport for 767. I was later made aware that the [Company Ops Spec] certificate restricted 767 aircraft from using this airport as an alternate only. In the future; we as flight crew and scheduling should pay closer attention to the operations permitted in the certificate.
B767 First Officer reported having flown to destination that is not authorized in the company Ops Specs.
