If you're expecting a volunteering organisation to pay for your airfare too, that's is going to be very unlikely unless you're highly skilled in aspects of relief work such as a degree in medicine or mechanical / civil engineering. Most volunteering work that has a 'tourism' / experience component in it often indeed asks for you to pay for your expenses. In this regard, you're perhaps better off gaining an English as a Second Language (ESL) teacher certification and then applying for teaching jobs.
