This is taken straight from Avion rewards chart.
65,000 Long-haul: Europe From a major gateway in Canada/U.S. to select destinations in Europe $1,300
It costs 65,000 miles that will cover you up to $1,300 in ticket value..excluding taxes, because you have to pay them anyway. Any tricks, the only one that I came across when booking with them, is that they often don't have access to the super cheap fairs that we see through consolidators - do you research yourself before booking with flight numbers, dates, times etc taken from travel websites, makes it easier. They can honour cheap sales offered directly through the airlines, so if you see a fair on a airline site under $1,300 RBC will book it for you at that price.
I've never had any trouble booking for trips, and we are using them to go to Orlando in 4 weeks and have travelled to Australia with RBC..best thing I like is that you can also earn reward miles with other programs with these tickets because they are not classed as reward tickets.
