Best Time to Book
Buy your flight from Boston to Ottawa 36 days in advance for the best price; prices rise significantly if booked later.
For your trip from Boston to Ottawa, the ideal time to buy your ticket is 36 days before departure, when prices are at their lowest, around $428. Booking too early could cost you up to $580, while last-minute purchases within 19 days can soar to nearly $903. After 36 days, prices generally continue to rise, with a notable increase as departure approaches.
