If you have made a reservation for multiple people, you need to check in online for all the passengers and issue boarding passes (2D barcodes) for all of them.

Boarding passes (2D barcodes) can be saved as screenshots, etc., which can be shared among all the passengers on their smartphones or managed by one of them.

You will need to scan your boarding pass (2D barcode) when passing through the security checkpoint and boarding gate.

If one person is managing the boarding passes (2D barcodes) of other passengers together with their own one, that person may scan all the passengers’ boarding passes (2D barcodes).

In that case, all the passengers need to be present when passing through the security checkpoint and boarding gate.
