Conference/Training Organizers
Ask the organizers of the meeting or training you’d like to attend if travel support is available. Many times organizers have partial or full support available- especially for those participants that bring something extra such as speakers. Some conference venues offer free rooms and other perks to organizers, which is sometimes passed on to participants. Organizers such as the UN or Rockefeller Foundation own venues that can be made available free or at a subsidized rate.
Travel Vendors
Ask travel providers (airlines, hotels) for support, as they often sponsor NGO travelers. Check the corporate social responsibility page or sponsoring pages on their website – or call the local booking office. Some large travel agencies (and even smaller ones) provide reduced rates for NGOs or offer unpublished discounts. Examples of vendors that offer subsidized travel to NGOs include:
