How to get a recommendation letter for IATA TIDS?

Our agency is currently in a stage of development and expansion, especially after our recent move from the USA to the UK. At this moment, we operate under a whitelabel OTA model, where all travel services (hotels, flights, packages, tours, activities, and tickets) are fulfilled through trusted third‑party providers and partner platforms.

As part of this new chapter, we’re looking to obtain the free IATA TIDS registration (www.iata.org/en/services/travel-agency-program/tids/). We see it as an important step because many suppliers, partner programs, and affiliate platforms require agencies to be registered with a globally recognised organisation in order to access their programs.

At this moment, other internationally recognised accreditations are still out of reach for us, either because of the high subscription costs or because the requirements don’t yet match our current stage of growth. TIDS seems like the most realistic and strategic option for us right now.

One of the requirements for IATA TIDS is providing a letter of recommendation from a company already recognised by IATA. This is the part where we’re a bit stuck.

Does anyone know how to obtain this letter, or who we might approach for it? If someone in this community is able to issue such a letter, or can share how they managed this step themselves, it would be incredibly helpful. We’re also open to hearing about alternative certifications or recognitions that serve a similar purpose for small but growing agencies.

Thank you very much for any guidance, ideas, or experiences you can share!
