Seems quite a positive review . Norwegian gets a decent name but occasionally there are delays.
A few weeks ago , the service ex Gatwick had technical problems and that mean the Ezeiza - Gatwick service was cancelled. Some of the Argie journalists said that they did not inform the travelers until they were at the airport . , but others said they look after them properly.
