I want to fly on that specific day so asked the agent to change the origin to AMS. According to the agent this normally isn't possible, since coupons do not allow reroutes. After checking this with Miles+Bonus she was able to switch me (including the upgraded seat) to the AMS flight. Even though there was no I class available!

Very happy with the resolution.
