The International Organization for Migration (IOM) is an intergovernmental organization established in 1951, IOM is committed to the principle that humane and orderly migration benefits migrants and society.
Some of its main benefits are:
- Preferential air fares

But as with anything, also check with a travel agent, to ensure you really are getting a competitive price.
