Using messaging for customer service in the Messages app on an iPhone or other iOS device allows customers to easily save a history of their chats with customer service.
And Delta said it expects increased use of a virtual assistant for basic questions would reduce wait times for customer service across the board.
Customers will also have the option to ask to speak with a live representative, according to the airline.
“We want Delta customers to feel in full control of their experience with Delta, but know that we’re just a click or tap away when they need us,” said Delta’s vice president of distribution and digital channels Rhonda Crawford in a written statement.
Delta already had an option on the desktop version of its website to chat with a virtual assistant or reservations specialist.
Last year, the online chat service Delta used was affected by a cyber security breach that put some customer payment information at risk. That breach involved a different provider, 7.ai.
