If you buy one of these long-haul HBO fares but actually need to take a bag each way, is there a standard charge rate for adding a bag to a booking?
I've seen conflicting information on the BA website.
One place says that it is £40 for the first bag and £60 per bag thereafter, but when I tried a dummy booking it seemed to vary significantly.
The routes I fly regularly have a price difference of over £250 between the basic and standard economy fares, so being able to limit the damage to £80 return would be very useful.

I have to agree on the rubbishness of the new website for the economy end of the market though. Having to click through every single flight option to find out the actual prices is a real pain.
