SIAMA stands for Society for the Interest of Active Missionaries Abroad and was founded in 1970!

SIAMA is a travel operator, which exclusively takes care of air travel for Missionaries, retired Missionaries, Non-profit Development Workers, Bible School Students, Speakers at Religious Conventions and many others who contribute to better our world society.
We are dedicated to provide you with the best possible prices and travel arrangements so that your funds can be saved as much as possible for other worthwhile matters in your Mission-Development-Charity work.

A large number of First Class Airlines, like British Airways, American Airlines, Air France, KLM, Lufthansa, Swiss and many more, have a good heart for SIAMA because of our specific goals to serve you. They give us the opportunity to provide you not only with competitive airfares, but also with special advantages, like flexibility on tickets (date changes for free or at low cost), extra baggage allowance, low cancellation fee and a year validity on roundtrip tickets.

Especially for complicated routings and one way tickets you will notice SIAMA can offer you very advantageous prices. Therefore when you have a special routing or request (more luggage allowance, flexible tickets), we are specialized to assist you and can save you the hassle to browse for all sorts of flight booking websites to find the best rates. It is our Mission to help Missionaries!

If you are in need for air travel, give us a chance to surprise you!
