I had to go through facility 1 because I was only flying with Avianca Airlines out of the Avianca Airlines YYZ terminal. This terminal, which is well-known for its modern appearance and ease of use, made the entire process—from check-in to boarding—smooth and stress-free. The convenient Avianca check-in counters and the terminal's assortment of amenities, including as food and shopping options, made my flight delay enjoyable. The kind staff at Terminal 1 and its well-organized structure made my journey with Avianca Airlines a pleasant beginning.
