The bodies were located in the wheel well area at Fort Lauderdale-Hollywood International Airport. It's the second time over the past month that a body has been found in the wheel well of an airplane.

JetBlue and Spirit said it'd be best if they remain separate companies as they don't believe they'll be able to merge by the time the agreement is up in July.

JetBlue, the nation's sixth-largest airline, sought to buy Spirit for $3.8 billion. The judge said "the consumers that rely on Spirit's unique, low-price model would likely be harmed."

JetBlue said Monday that CEO Robin Hayes will step down next month and be replaced by the airline's president, Joanna Geraghty, who will be the first woman to lead a major U.S. carrier.

The ruling is a major victory for the Biden administration, which has used aggressive enforcement of antitrust laws to fight against mergers and other arrangements between large corporations.

The Biden administration sued on Tuesday to block the $3.8 billion purchase, saying the deal would reduce competition and drive up air fares for consumers.

The agreement Thursday capped a months-long bidding war and arrives one day after Spirit's attempt to merge with Frontier Airlines fell apart. The deal still needs approval from antitrust regulators.
