The trip designer is remunerated with the commissions on the services he includes in his circuits but doesn't produce. This commission usually makes up for 7% of a service.
The travel planner can also include services he provides himself, like an airport welcome, guided tour, etc. He sets the price of these services himself and we take 10% of that price.
Therefore, the remuneration for a travel designer depends on the service and who produces it. For a whole trip, his pay will be composed of the commissions on the services he doesn't provide and 90% of the price of the services he provides himself.
