Good idea, Alexandra. I just booked a UAL award flight departing at 5:45pm as a back up. Economy plus exit row for 55K, not bad considering they want 140K for premium econ and 200K for business. It is a 9 hour flight to SFO, so I should survive if I miss my EVA business class flight. I just have to remember to cancel it, if I get on the EVA flight.
