One of the tricky problems was that when I was on the phone talking to an agent their system did not allow me to book the flight MAD-HKG on CX with the connection time >2hrs while the flight was available when I search it separately. I double checked the MCT in MAD was 90min if I remember correctly. The agent said "Wait a moment" and then the problem solved.
Another problem I have encountered was that the flight OPO-MAD is operated by Air Nostrum, marketed by Iberia. The agent said it's a codeshare flight so she could not book that. I told her Air Nostrum is an affiliate airline of IB and it's also under the oneworld alliance. She said "wait a moment please" and then another problem solved.
