No. You pay the price the operator lists, there's no fee added for using us, and we don't put commission on top of your fare. Booking direct doesn't get you a lower number. Sometimes an agent can access a better price than the one on the operator's own site.
On top of the same fare, working through an agent often comes with things the operator won't hand a direct booker: onboard credit, occasional cabin upgrades, and sometimes local gear rental thrown in.
There's also a category of help operators simply won't provide once your booking is confirmed. Packing questions, tipping norms, what charging blocks to bring, adding Patagonia or Iguazu either side of the trip. Operators routinely tell direct bookers to go and find a travel agent for that anyway.
