Cash upgrades?
Hey guys,
I'm flying LHR-DXB on Qantas next week. I'm on a business class award ticket (booking class U) - booked with Avios via BA.com. I'd like to upgrade to first either with cash or my avios. Firstly, is it possible with my booking class, and secondly how much can I expect to pay in cash / avios?
Thanks in advance.
