What is an e-ticket? Ctrip sent me a message. Is this an electronic ticket?

After booking a plane ticket online and paying successfully,

Ctrip will first send an order message to your designated mobile phone via SMS.

You can open your reservation details according to the order number on your computer.

When opened, it will display your reservation information, including flight, take-off and landing time, passenger information and so on.

Click Print to list your e-tickets.

Please take this printed e-ticket to the airline counter for check-in on the day of flight departure.

In fact, the website will send your information to the airline after your reservation payment is successful.

You go to the airline with an e-ticket just for the convenience of the service staff to check in.

Even if you don't have an e-ticket, as long as you remember the flight and departure time of the airline, you can check in with your personal ID card, because your information has been logged in and put on record, and the airline counter only does a confirmation procedure, or you can find your information according to the order number to confirm your identity.
