Cancelled, the connecting flight from Dubai to Shanghai on Emirates Airlines on May 5 has been cancelled, just cancelled the ticket, Qunar said that I can only refund the second half of the ticket, confused, can a single airline in a single order only refund part of the connecting flight when the second half of the flight is cancelled ?

It's probably that your ticket is issued separately. Airlines generally require a full refund for unused connecting flights. You can file a complaint if you bought the ticket on a domestic website. According to regulations, tickets issued before January 24th should be refunded in full.

Are the policies of different airlines different? When I cancelled my Lufthansa ticket, I was required to cancel it in full. I couldn't just cancel the flight from Frankfurt to domestic, I had to cancel the flight from Helsinki to Frankfurt together.
