Air Canada may have an issue with pilots bringing porn onto its airplanes … and one XXX site is so appreciative it’s offering a special deal to any of the company’s wingmen — with a catch.

Brazzers says they’ll hook up ANY Air Canada pilot with a free membership … and it won’t expire until they stop working for the company. Only problem … they have to reach out via Twitter — which is extremely public.

According to the CBC … a memo went out to Air Canada employees last year instructing pilots to stop bringing porn into the cockpit — four months later, someone else got caught breaking the rules.

Joey … you ever seen a grown man naked?
