The newest update to Apple Maps can actually help you navigate inside the airport. The maps have the ability to point out important spots that the traveler might need, such as terminals, gate numbers, security checkpoints, baggage claim areas, certain stores, restrooms, and restaurants.
The feature is not yet available at every airport, but it can currently be used at the airports in San Jose, Philadelphia, Oakland, Miami, Minneapolis-St. Paul, Baltimore, Portland, Las Vegas, and Chicago.
Other cities that could soon be added include New York, Amsterdam, Berlin, Denver, Detroit, Dubai, Hong Kong, Houston, Indianapolis, London, Los Angeles, Newark, Pittsburgh, Seattle, Toronto, and Vancouver.
Some airports are quite large and it can take a moment to orient, but it will be interesting to see how many people will find this feature necessary to get around.
