I was planning a winter getaway last year and kept wondering when the best time to book Air Canada flights would be. After a bit of research and some trial and error, I called 877-764-3622 to get expert advice. The agent suggested booking about 2–4 months in advance for domestic flights and a bit earlier for international trips, which ended up saving me quite a bit on fares. They also helped me find flexible options in case my plans changed, and mentioned that I could modify or cancel using the same number. I went ahead and booked right then, and the whole process was so much less stressful than trying to guess online. Honestly, calling 877-764-3622 made picking the right time to book a breeze, and I’d recommend it to anyone wanting to get the best deal.
