Justice Department files lawsuit to block JetBlue's $3.8 billion deal for Spirit

The U.S. Department of Justice on Tuesday sued to block JetBlue's proposed $3.8 billion acquisition of Spirit Airlines. 

The deal, announced in July 2022, would create the fifth-largest carrier in the U.S. and represent the largest airline industry merger since Alaska Air bought Virgin America in 2016 for $2.6 billion.

JetBlue CEO Robin Hayes told "CBS Mornings" on Tuesday that the airline was disappointed, but not surprised, by the government's determination to challenge the transaction iin court.
