TD Cowen increased its price target on Delta Air Lines (DAL) to $77 from $72, reiterating a "buy" rating for the carrier. The new target implies a potential upside of approximately 14% from the stock's prior close. This analyst update is part of a trend of positive sentiment, with other firms like UBS and Bank of America also recently lifting their targets. The consensus rating among analysts remains a "Buy." Separately, Delta experienced a brief operational issue, temporarily halting its flights at the Detroit airport due to a technical connectivity problem. The ground stop was resolved the same day, but led to 36 flight cancellations and 97 delays. Delta issued a travel waiver for customers affected by the disruption at one of its major hubs. No reports immediately detailed a significant market reaction to these events.
