The 10 club point earning rate on these regional fanfare economy tickets was small but it was an nice enhancement added as part of the April MPC changes. Premise being MPC giving something small back to economy travellers while taking away a large chunk of club point earning for long haul.
I wouldn't dream of trying to make gold / diamond exclusively with fanfares but it was a nice extra when you were travelling around 10-15 fanfare trips per year.
