Call me gullible but I looked at the EOS website and was impressed with their money-back guarantee for BA or VS flyers, if you have two transatlantic flights in J (or better for BA) on those airlines in the last 6 months EOS offers a 100% satisfaction or money-back guarantee on your first EOS flight.
It's obvious what's going on there and what that's directed to but hey, a money-back guarantee is a money-back guarantee. And I didn't notice any fine print.
