A travel transaction is similar to a credit or debit card transaction. Each time someone in the world pays for something as simple as a cup of coffee the bank that issued the credit or debit card gets a percentage of the sale from the coffee shop. The same is true in the travel business, each time you make a simple reservation for a customer you will receive a percentage of the sale (a commission payment) direct-deposited to your bank account. If you love to travel this is a much better way to reach your goals than to accrue points or frequent flyer miles.
