Delta Air Lines is seeing more sectors that had lagged the broader return to corporate travel starting to once again hit the skies, Chief Executive Ed Bastian tells analysts on a conference call. “We’re finally starting to see the tech companies traveling again,” he says. The airline is also seeing a rise in travel from consulting firms, which Bastian says also lagged the broader state of corporate travel last year. The auto sector has also recovered from the labor strikes last year and executives have begun traveling once again, he says, as has the entertainment sector. Shares fall 8% on a bleak profit forecast.
