WASHINGTON (Reuters) - Families for some of the 346 people killed in two fatal Boeing 737 MAX crashes said on Wednesday a U.S. judge should reject the planemaker's proposed plea deal with the Justice Department and said the government should seek a much higher fine.

On July 24, the planemaker finalized an agreement to plead guilty to a criminal fraud conspiracy charge and pay between $243.6 million to $487 million after breaching a 2021 deferred prosecution agreement.
