I am flying to London from Toronto on March 13th, the flight in Economy is sold out. There are lots of seats in Business left. I got two Special Certs with my 2009 Elite Areoplan membership.

I used one already on a flight in March, and want to use one again, the thing is my wife is coming too and I only have one cert left. Does anyone know if there is room on the day of the flight if they'd allow her to be upgraded?

Or is there anyway to get another Special Cert?

Thanks.
