The recently enabled airports include Charlotte Douglas International in North Carolina, Montréal–Pierre Elliott Trudeau International and Québec City Jean Lesage International in Canada, and Taoyuan International in Taiwan.
When searching for those airports, Apple Maps users can tap "look inside" or simply zoom in to view terminals, boarding gates, security checkpoints, airline check-in desks, baggage claim carousels, information kiosks, restrooms, stores, restaurants, parking garages, and even escalators, elevators, and stairs.
An indoor map is also now available at the Trinity Leeds shopping center in England, according to Apple's iOS feature availability page.
Indoor maps at shopping malls make it easier to find the exact location of stores, restaurants, restrooms, escalators, elevators, and stairs on each floor. The feature enables users to filter stores by categories, such as clothes, shoes, accessories, beauty, food, and drinks, with detailed place cards for each.
When the feature launched with iOS 11, indoor maps were only available in a handful of airports and shopping malls around the world, but Apple has been steadily adding locations over the past year.
The list includes airports and shopping malls in select cities across North America and Europe, including Baltimore, Berlin, Boston, Chicago, Dallas, Houston, London, Los Angeles, New York, Philadelphia, Portland, San Jose, San Francisco, Seattle, Toronto, and Washington, DC.
