I'd be careful of accepting the "free business class tickets" as the text indicates clearly this is space available upgrades (ie confirmed on the day only) and not business class tickets.
Interesting… my take on the text was quite different. I thought it was a free round-trip biz class ticket, which would be subject to regular seat availability at time of booking, with the voucher for the two free tickets to be issued at the airport!
Your take makes more sense!
