could anyone confirm what the fees/taxes and Avios difference would be for:

SFO - LHR off peak originally booked in Club World then moved into First when availability opened up?

The original booking was LHR - SEA (also in First) then the SFO - LHR leg using an AMEX 241 for 2 adults and one baby. The LHR - SEA leg was a peak date if relevant. Initial Avios cost was 209k when using the 241.

Thank you
