The amount you are paid depends on two variables: how much volume the booking produced and your current rank.
Every travel booking produces a different amount of volume. As a purely hypothetical example, one hotel booking might produce $20 in volume while another hotel booking might produce $50 in volume.
Whatever volume is generated by the booking goes into the compensation plan.
Once the volume is in the compensation plan you are paid based on your rank as you are with all other volume. For example, if you are at the rank of Marketer and the travel volume is on your level 2, you would be paid 5% on the travel volume.
