During a layover at London Heathrow Airport, I had the opportunity to visit the Air Canada Maple Leaf Lounge. The lounge offers a spacious and comfortable seating area with a view of the planes on the tarmac, a standard buffet with hot meals, a full-service bar and self-serve section. One highlight is the availability of several showers.The lounge offers a welcome break from the crowds at Heathrow Airport.
