Hello, am new and apologise if this has been answered.
1. If you buy a part cash part Avios fare can you then use a GUF2 to upgrade that? So economy to premium economy with the original booking and thenGUF2 to club?
2. Irrespective of the above, a separate question...Can you SPLIT the use of your GUF2 so that, on the same flight, one underlying cash ticket is upgraded and one ticket booked entirely on Avios is upgraded? I have plenty of Avios and would like to buy my companion ticket with them, whilst paying cash for my own before applying the GUF2 to both. Is that possible?
Many thanks to anyone who can advise...!
