15% off code - only work for round trip?
 

I got this 15% off code from a pilot friend. I'm planning to use it on YVR-CDG then ZRH-YVR. The code cannot be used on AC.com if open-jaw. Do you know if there's a way to workaround this? Thanks!

As far as I know, discount codes only work for round-trip or one-way. So you might be out of luck here. The best you can do is to buy 2 tickets and use the discount code on the one with the highest ticket price before taxes.

I'm not 100% sure if you can do this but:
Book YVR-YYZ-ZRH-ZRH-YYZ-YVR online using the coupon.
Immediately call AC res to change your itin to what you want. The coupon may stick.

If it doesn't, you can cancel everything and not have lost anything.

or take the TGV ZRH to CDG. Zurich Airport has a train station.
