Australia's flag carrier Qantas Airways said on Friday it does not expect an impact on customers from a strike planned by some of its engineering work groups ahead of the annual general meeting scheduled for later in the day.

Peak hour flights could be affected as hundreds of Qantas engineers are set to walk off the job for the second time in a month over alleged pay disputes.

The new Australia Travel Declaration will be rolled out from later this year on selected international flights.

A lightning strike by Qantas engineers is set to cause chaos across Australia on Wednesday and Thursday.  Around 300 Qantas engineers across Australia will walk off the job for 24 hours from Wednesday morning.
