The flight of Jixiang Airlines has been cancelled. Give me protection for Eastern Airlines. Is it reliable?

Generally, civil aviation can be changed, as long as an agreement is signed. However, in order to ensure the interests of passengers on the original flight, passengers who have changed their flights must be arranged on the contracted airlines' planes that are not full. The flight attendance rate is also dynamic, not the ticketing rate, which can only be known when you check in on the same day. Good luck!
