A good question, but I would hazard a guess that they won't refund people. We booked with BA last year and they didn't increase the price of our ticket when the levies went up.
To be realistic I wouldn't have thought so either Richard. Would be a nice gesture though, to refund money that they are now saying they no longer need. Maybe some people-power is needed again?
Well,
Its down to the luck of the draw.
Should we have "people power" to make those who booked and paid in advance so did not have to pay the surcharge pay up as well?
