I asked today and told me NO WAY Iberia can issue a paper ticket for OAL employees, even if the ticket is already issued.
When we issue paper tickets, we do not even create a PNR, we do it on a "temporary ticket mode" which allows to issue paper coupons with OPEN segments.
In IB we issue ZED tkts always OPEN, so there is no way to retreave the PNR somewhere else as there is no PNR created.

In a case they could retrieve anything for you it would be an electronic ticket, which can be retreived and printed out. We do have several electronic ZED agreements.

Call reservation number and ask there you transfer you to the employee travel line if you want to try.
