Interesting... How are you performing the bookings? Are you registered as a travel agent with GDS access? Or are you going through an other agency?
In general, travel agents that only use GDS don't have access to budget airlines such as Easyjet or alternative accommodations such as Airbnb or Sonder.
Extra question: how do you manage the non-gds content? Do you ask your travel agency to add remarks to the PNR, or have you built your own database to track these “PNR+extra” bookings?
Sorry, lots of questions but it’s a really interesting idea!
And yeah, we have our own database for everything. GDS is just one way to book and a "portal to the airlines" for us
