I wanted to close this out. I don’t remember my exact original booking class it was somewhere in economy. Upon checkin on my flight down to RAK I was given a special offer to upgrade to Biz class for £99. So I did it. This was given me a U class ticket. Which clearly didn’t matter in BA system. On the ticket I upgraded I was given full Biz class of service bonus on miles. You can see the difference down below.
