I'm looking to travel SYD-LHR in early December for a month and was looking to book 2 F seats (i have approx 1.1m points). As a silver member ive been watching closely for any seats appearing and am yet to see anything. With the QF companion sale on i'm contemplating booking the seats with cash and points (horrible conversion rate). My question to the community is would it be likely for F seats to appear later in the year or should i just purchase via the companion sale as the pricing ($11k a seat) is the cheapest ive seen. I guess the other option is to but J seats and upgrade to F but i'm guessing that securing two F upgrades as silver would be low. Appreciate the assistance as a first time poster.
