They would not be able to see the E-Ticket since AY is not yet part of the OneWorld E-Ticket environment. Therefore I had to pay for a paper ticket to be ussued.
If it's no fault of yours that the airlines have to issue a paper ticket, then you do not have to pay for it.
AY uses AMADEUS. The SAME system as QANTAS, BRITISH AIRWAYS and IBERIA. So it does not make sense to reason that AY would not be able to see the booking. In fact when QF makes the booking, AY would be able to see the ENTIRE PNR as it is the same PNR # as BA, IB and QF all together!
