I have an Old Account. Promotion Avios posted, and I have used them all up for an IB metal trip in 2019.
Now trying to price up an RJ return and I get as far as selecting the flights - then clicking on "View" brings up the same error message mentioned here already.
I can see the price for the same RJ return on ba.com
Is there a way to know whether the cash element will be materially less using IB?
