Will you send a text message to inform the boarding passengers before the plane takes off? Can I still find the valid information of the ticket online after the refund of the electronic ticket?

Under normal circumstances, it will. I will send a message to inform you of the flight booked on that day and remind you how long it will take to check in at the airport! But there are exceptions (of course, this situation is rare)! After the refund, you can still find your refund information in the order management of your refund website! And your ticket number at that time, and so on! ! !
