I don't want to board the international flight of China Eastern Airlines. Will there be any news to inform me of the mobile phone number where I bought the ticket?

There will be no notice for those who have not boarded the plane. Generally speaking, airlines will cancel flights, change flight schedules, or encounter irresistible natural disasters that affect normal flight plans, or flights are oversold, and mobile phone numbers that buy tickets will receive notification messages. Other circumstances, such as you don't want to go or miss the plane, the general airline will not inform you.
