Qantas Airways’ pilots union has warned of looming risks to flight safety — from crew fatigue to looser landing rules in Australia — as a travel rebound stretches an industry still fragile from the pandemic.

With domestic travel restrictions eased, passenger demand in Australia exceeds 2019 levels and Qantas and smaller rival Virgin Australia are ordering new planes for a post-COVID era. But there are concerns some proposals to handle the faster-than-expected recovery may be too much for a global workforce decimated by layoffs and bereft of its most experienced pilots.

A proposal by Brisbane Airport, for example, to breach international protocol and allow planes to land with stronger tailwinds in order to accommodate more air traffic raises the chance of a mistake, particularly by foreign airline crew, said Tony Lucas, president of Qantas union, the Australian & International Pilots Association. Normal practice is to take off and land against the wind. The union represents more than 7,100 commercial pilots.
