A lawyer representing more than three dozen families whose loved ones were lost in the Germanwings plane crash in March says his clients want to sue for compensation in the United States, where courts could decide upon much larger settlements.

German lawyer Elmar Giemulla told the dpa news agency on Sunday that 100 of his clients from 39 families gave him the go-ahead to pursue legal action in the U.S. at a Saturday meeting.

Prosecutors believe the Airbus A320 was intentionally crashed by its co-pilot, killing all 150 people on board the Germanwings Barcelona to Duesseldorf flight.

Lufthansa has offered around 100,000 euros ($108,000) per family, depending on its size. Giemulla says the offer is far too low.

Giemulla says he will talk again with Lufthansa before filing any suit.
