Can I buy a plane ticket on Taobao?

Of course. Log in to Taobao, click Ali Travel, which is convenient for ordering;

After you have successfully purchased the air ticket, you will receive a short message from Taobao, or go to the page of "My Taobao"-"I am a buyer"-"My air ticket/hotel/insurance" to check the successful ticketing status of the air ticket order. You don't need to take the plane ticket. You can check in at the airport check-in counter with your ID card before taking off.
