Delta Airlines this week dropped the biggest hint of this when it announced deployment of 19,000 iPhone 12s for its in-flight staff

Delta plans to use iPhones to offer immersive training experiences to staffers, featuring video, photos, and AR. Specifically, it plans to use AR to help cabin staff quickly locate where items are stowed – useful for hand luggage but even more useful when attempting to locate a flight’s worth of desserts for the meal.
