I am a Canadian international student who will be studying in Sydney for the next 6 years. My home is in Toronto and I can also fly out of the Buffalo airport. For the next 6 years, I will be flying back to Canada ( to either Toronto or Buffalo) around early December and I will be flying to Sydney around mid February. Being a poor student, I would like to get the least expensive flight possible. I do not mind having more stopovers if it will lower my cost. I thank you in advance for any advice and tips.
