i purchased two tickets and upgraded to CW for my future parent in laws.but a family member fell ill and they had to change dates. one day has reward seats in CW. but I wasn;t sure will i do a cash upgrade so both legs can be CW or just do one avios flight so one leg would be PE and the return is CW.
While they were checking the cost to upgrade by cash. They held the seats for me. It took them almost a week to get back to me, but they assured me that once the seats were held until they got back to me they wont be given to other people. And that was true!
my only problem was that it takes AAGGES to get to an agent on the phoneline to get them to save the seats for me!
