The CEO of Lufthansa is holding a press conference on the Alps plane crash.
Carsten Spohr said the last few hours have been the darkest in the company's 60-year history.
Mr Spohr has described the "emotional and difficult" meeting with bereaved families of the victims in Barcelona.
He said families will be flown to Marseilles tomorrow so that they can visit the crash site.
Mr Spohr - a former pilot himself - said the plane was in perfect condition and he can't understand how the crash happened with two experienced pilots.
During a visit to the crash site, the boss of Lufthansa has avoided reporters' questions about the co-pilot's known depression.
Newly-released footage shows Germanwings co-pilot Andreas Lubitz in flight around ten years ago during his time as a trainee.
Pilots with a history of depression should not be banned from flying, a leading British psychiatrist has said.
