Thanks. I figured I wasn't going to find all flights with F options but still a shame QF and QR are not offering them currently. It might still work as my itinerary includes SE Asia, Middle East and Europe.I am about to start booking and the preference is F. The F options are available but are slim as QF and QR are currently not operating aircraft with F seating. JL, CX and AA offer F on most of their 777-300 and BA has F on their 777-300, some 777-200, the 787-10 and 787-9. When booking the F option will show as available or not. I will be taking the punt on F however the issue that may come to light is carriers could swap aircraft to one that does not offer F. It is not an indication of what travel will be like in 12 months but looking at FR24 carriers such as CX and JL who publish F seat availability on certain routes have been using the a350 and 787 which do not have F cabins. Booking F is a bit of a risk as you have used the points but may be downgraded to J.
I'll post a proposed one soon for feedback.
