As mentioned there's no lounge passes but keep an eye out for upgrade offers. You need to be in business class (Club World/Biz Bed) or higher for lounge access.
I'm guessing you're flying Openskies due to the Orly reference, but if you're flying BA mainline (i.e. via LHR) you could do a cheap CE upgrade ORY-LHR to get lounge access in Orly.
