- I had a seamless and effective encounter with the Air Canada LHR Terminal. Passengers received prompt assistance from amiable workers during the well-organized check-in process. Although lengthy, security lines went quickly. The station itself was clean and modern, with lots of places to sit, buy, and dine. Clear announcements and preferential boarding for qualified passengers were features of the well-organized boarding process. The seamless experience before departure was ensured by the professional and helpful Air Canada ground crew. All things considered, my flight with Air Canada through LHR was enjoyable, and I would be delighted to do so once more in the future.
