Air China has become the latest airline to allow customers to check-in via simple SMS and mobile barcodes. It is initially only available on Tibetan flights and direct flights from Beijing, and only for passengers who booked their tickets via the Air China website.
Once a traveller has booked their ticket on-line, they can choose to be sent an SMS anytime from 24 hours to 90 mins before there flight. That SMS contains a link leading to a mobile barcode, which the passenger can use to check through all necessary security gates and onto the place itself.
