Hello! First post here but learned so much from this forum already! Tried to find the answer in the t&cs or in other companion voucher threads but couldn’t - apologies if I missed it somewhere.

I am wondering if it is possible to do an open-jaw returning to a non-UK airport with a companion voucher, eg JER-LHR-SFO outbound, LAX-LHR-CDG return. I know there are ways of doing it on separate tickets which don’t cost extra (assuming I won’t need hold luggage and can skip a potentially useless return leg to JER) but would rather do it on one ticket to CDG for the extra protections that brings - is that possible?

Thanks in advance for any advice!
