What information can passengers expect to find on Blue Stripe signage?

Blue Stripe signage at O'Hare Airport is specifically designed to provide passengers with essential information related to navigating the airport efficiently. Passengers can expect to find directions that help guide them to various terminals, gates, and amenities within the airport. Additionally, it includes terminal information that informs travelers about the services available in each terminal, such as check-in locations, security checkpoints, and available airline facilities. Service updates are also included on these signs, which can inform passengers of any changes, such as delays or important notices related to their travel.

In contrast, while flight departure times are crucial for passengers, they are typically displayed on separate digital boards rather than on Blue Stripe signage. Weather forecasts, while important for travelers, are not usually part of the airport's wayfinding signage. Lastly, shopping and restaurant advertisements are generally not included on Blue Stripe signage, which focuses more on providing practical guidance and service-related information rather than commercial promotions. Thus, the correct choice encapsulates the primary function of Blue Stripe signage in aiding passenger navigation and providing relevant updates.
