About SIAMA
Your Trusted Partner in Missionary and Humanitarian Travel
Since 1970, SIAMA has been supporting missionaries, aid workers, and non-profit organizations on their journeys worldwide. We understand that humanitarian travel is never just a regular flight; it is a mission with a purpose.
Behind SIAMA is a dedicated team of specialized travel consultants who know the complexities of field travel inside out. We combine decades of industry expertise with a deeply personal approach, ensuring your focus remains entirely on your work.
Why Missionary and Humanitarian Organizations Trust SIAMA
Decades of Expertise & Worldwide Reach
With over 50 years of experience, we have built strong partnerships with major international airlines. This allows us to secure specialized flexible airfares, extra baggage allowances, and lenient cancellation policies tailored specifically for aid workers.
Personal Support When It Matters Most
Travel plans in the humanitarian sector can change in an instant. When severe weather hits, flight schedules shift, or political situations arise, you do not reach an automated call center. You get direct access to our experienced team, ready to rebook and resolve issues immediately.
