Delta Faces US Investigation Over Handling of System Outage.

Delta Air Lines is being investigated by US authorities over its handling of a technology glitch that resulted in thousands of canceled flights. The Department of Transportation has initiated the probe to ensure that the airline is complying with the law and taking care of its passengers during the ongoing disruptions. Delta has experienced the most significant impact among US carriers, with over 5,400 grounded trips since the breakdown on Friday. Customers have expressed frustration on social media, citing canceled flights, lost baggage, and a lack of food and hotel vouchers. Delta's recovery has been delayed due to the impact on its internal system for processing flight and crew changes. [Extracted from the article]
