I've been trying to book a flight home for a friend for the summer but I keep getting fares in the $1700+ range out of YYZ. When I check fares out of BUF or ORD they are about $700 cheaper. Does anybody have any ideas on how I can get a cheaper fare out of YYZ. Travel dates are flexible but preferably around April 20th and back on Sept 1st. Any help would be appreciated.
