1. SMS is fake: some criminals will send fake SMS pretending to be airlines to defraud money or personal information. Therefore, for the time being, you can not trust the SMS, and check the ticket order through the official channel of Sichuan Airlines.
2. Delay in updating order information: Sometimes, official website of the airline may not update your order information. You can wait a while before trying to inquire, or contact Sichuan Airlines customer service for consultation.
3. Your order may be cancelled or modified: If your order is cancelled or modified, Sichuan Airlines may place a new order first, but the old order information may not be updated in time. You can check your email or contact the customer service of Sichuan Airlines to confirm the status of your order.
4. Your order may be mistaken as invalid: Sometimes, some orders may be mistaken as invalid, for example, because the wrong information is entered or the regulations of the airline are not met. You can contact Sichuan Airlines customer service, provide your own order number and check the order status.
In short, if you can't find your order information on Sichuan Airlines official website, you'd better contact Sichuan Airlines customer service directly and provide your order number and personal information for help.
