I signed up for this as I currently have no status and am flying with QR later this month. The main reason I signed up is that I read you can use the Business class check in desks and I'm having pain while standing at the moment so the less waiting in line I have to do, the better! When I purchased the tix, I put in my BA FF number for miles to be credited there. Will I need to change this to TopBonus or even QR to use the business class check in desk? Is it just sufficient to line up and then show the card as to the reason I am in the business class line with a Y ticket. If it makes any difference I am flying BCN - DOH.

Thanks
