The flight Jan 5. NORWEGIAN DY7012 was cancelled after several hours of waiting. The passengers could not get the baggage already in the plane when leaving the airport after 12 hours of waiting at the airport. They told the passengers to later get thrir luggage or that it would be delivered to their destination. My daughter returned to the airport hours later just to get the bag but the baggage from that cancelled plane had not yet arrived to the baggage hall area. My daughter had to move on to the Newark airport for her new booked Icelandair flight. The Norwegian baggage staff at JFK asked her to make a claim (tag: DY457177, grey Samsonite) for Norwegian to be able to carry the baggage to the destination intended, Helsinki. They promised the baggage would arrive to its destination Helsinki. My daughter had to then take the separate Icelandair plane to Helsinki and we are waiting for the baggage to arrive here. She made a separate claim in Helsinki also with lease locate the bag in JFK terminal 1 and please confirm when and how it will be delivered to Helsinki.
