Human Factors; Procedure
I was the First Officer on Aircraft X inbound to ZZZ [and outbound from it] in violation of [Company] Ops Spec and 14CFR 121.55. We were operating a 767 into and out of ZZZ for these flights. For the B767; ZZZ authorization was for use as an Alternate only. It is very difficult to be aware of every airfield in [Ops Specs] and its designation in regards to each fleet type. [Another aircraft we use] is used frequently to service ZZZ. There was never a concern that the B767 was not authorized. A trip in our published bid packet is assumed to be Ops Specs compliant. Therefore; I operated the flight inbound and outbound in violation. I was in error to make that assumption.
B767 First Officer reported landing at an airpor not authorized in company Ops Specs.
