Flight from Chicago O'Hare Airport to Ottawa

Verified travelerFlew with Air CanadaORD-YOWNov 2024

Ottawa, as a small airport is easiest to navigate! Overhead baggage compartments seem to be smaller, and on every flight they seem to need travellers to volunteer to put carryons in checked luggage instead.

Verified travelerFlew with United AirlinesORD-YOWJan 2024

I always expect issues with United but there doesn't seem to be another airline to use. Advice: Give yourself and extra day to get anywhere - don't be in a hurry to get home either.
