I just booked 2 OW UA flights EWR --> VCE in early April, Global First, with a stopover in FRA for 3 hours (looking forward to checking out that first class lounge!) for 67.5K each. The tickets are on hold until Friday. I realized that I have a wedding in LA a few weeks earlier. Is there a way to add a stopover from LAX --> NYC to tack onto my EWR --> VCE award flight? PUTPAC, or is there a different way?
