Its the devaluation possibility that concerns me for my miserable 160k of Avios.
It might be best to use them now and book flights, but that means getting in the hole with BA for another £500 to £600 for the cash element...
Difficult to know really...but I think that J and F travel aren't going to be the same after this anyway...with reduced service levels, but higher prices, to reflect people's desire for extra space in the cabin and the reduced chance of virus transmission.
Scoffing your F class taster menu through a cotton mask isn't going to be quite as fun...
