This inconvenience would not only be unpopular with customers, but it would also place Qantas at a competitive disadvantage with airlines such as Qatar Airways and Emirates, which also offer test-free one-stop routes from Australia to London for vaccinated passengers. Another testing problem awaits Qantas from the United Kingdom to Australia. Australia's pre-departure test requirement for fully vaccinated international visitors is one of two options: The issue for Qantas here is that those who choose a pre-departure PCR test three days before their flight departure from London to Australia, which complies with Australia's entry requirements, would not be eligible to transit via Singapore because the test was taken too early to meet the ICA's transit requirement (two days). This would require Qantas to announce a stricter pre-departure test requirement to all passengers travelling on QF2 (London – Sydney) services, resulting in daily confusion and drama at the check-in desk.
