This feels like it should be answered already but could not find it...

Just trying to make sense of the lower Avios awarded on some recent BA Holiday flight credits (i.e. not by spend).

They came out less than the same BA Holiday flights from last year, or BA direct flight bookings I made before October last year.

I have been BA Gold the whole time, and I can't see the old/higher values in the BA Avios checker tool today.
Seems like the mileage table was devalued at the switchover to eligible spend awards.

All flights are LHR-SOF (or SOF-LHR)
