We are planning a EWR-SYD RT in April. My plan is to apply Plus Points for all of us, and ordinarily I would book separate PNRs for each of the 4 pax (2 adults, 2 kids) to maximize upgrade chances. However I noticed that I am getting a decent discount via "Break from Business". My plan to to book the trip on a single PNR to get that discount (since the discount only applies on PNRs that include the primary discount eligible pax, which is me) and then call in to GS and have them split the res into 4 different PNRs, and then apply Plus Points. Is this a viable strategy?
