Qantas seems to have been left in an awkward situation after the release of the Apple Watch: its boarding passes can't be read by its scanners when displayed on the wearable device.

Since the Apple Watch became available on Friday, several users of the Qantas Airways app have run into a peculiar problem when attempting to use it at airports across the country.

Qantas's Apple Watch app.

The issue? The Apple Watch, together with a wrist, doesn't seem to fit in many of Qantas's fixed scanners at boarding gates and in lounges when presenting digital boarding passes in the form of QR codes sent across to the Passbook app by the Qantas app.

"@Qantas your scanners don't fit wrists with Apple Watches," Ben Crosby, of Sydney, wrote in a tweet to Qantas on Wednesday morning, adding that he "wasn't allowed" to take a picture.
