Each coupon code can also collect affiliate information in the background for control over affiliated bookings.
For example, you can agree with a local newspaper, promoter, beach-boy, etc. that for any passenger that he will refer to your company, the passenger will get a $10 discount. The referrer will get a 2% commission from the fare.
The AeroCRS reporting center will help you keep track and credit the referrers, positions, and more, giving you a significant marketing advantage.
