No more "we'll call you back". Done. Replacing humans. Delta is pushing this app as a convenience. But when the app says they cancelled your flight, and wait times are over an hour on the phone... How is this app helpful? Delta, we want to talk with real humans. Truthfully, delta appears best shamed into response on Twitter. Which is super sad... That only public lambasting can spur them to response. But at least there is a human on Twitter. Even if only one for every ten conversations.
