When someone clicks your link, Fernwayer places a tracking cookie that lasts 60 days.
If they book any time within those 60 days, you're credited with the referral — even if they didn't book on their first visit. The clock starts the moment they click.
Why 60 days
Most travel affiliate programs give you 30 days. Fernwayer gives you 60.
The reason is the kind of travel Fernwayer is. A private Experience with a local maker isn't an impulse buy — people research, plan around dates, and often decide over weeks rather than minutes. A longer window means your recommendation still counts when your reader finally books, not just if they book right away.
