summarize this please: Delta Air Lines has been leveraging artificial intelligence (AI) in several ways to enhance its operations and customer experience: Operational Decision Making: Delta has developed an industry-first machine learning platform that uses AI to improve operational decision-making1. This platform analyzes millions of operational data points, such as aircraft positions, flight crew restrictions, and airport conditions, to create hypothetical outcomes. These outcomes help Delta's professionals make critical decisions before, during, and after large-scale disruptions, like severe winter weather or a volcanic eruption1. Digital Simulation Environment: Delta is creating a full-scale digital simulation environment for its global operation, a first in commercial passenger aviation1. This environment uses Delta's historical data to simulate operating challenges and provide likely outcomes to lessen customer impact1. Pricing: Delta has begun experimenting with using AI for its pricing2. AI could help determine the amount consumers are willing to pay for the airline's premium products, relative to its base fares2. Customer Service: Delta's initial foray into AI is on the customer service side, working with its reservations team2. These initiatives are part of Delta's overall investments in digital technology, and the company expects these efforts to increase the value of their operations over time2.
