Many of the passengers' families have been huddled in a Beijing hotel where they have publicly complained about the lack of progress in finding the plane and accused the Malaysian government of withholding information and botching the investigation.
Lawyers have arrived at the hotel seeking to represent families in lawsuits against various stakeholders in the plane's disappearance, including U.S. company Boeing.
