Luxembourg in May had introduced quarantine rules, obliging arrivals to take a PCR test upon entering the country, followed by a 7-day quarantine period that was only lifted following a second negative test.
The measures have now been scrapped, the government said in a press release on Wednesday.
However, anyone aged 12 or over travelling to Luxembourg by airplane will still need to provide a vaccination, test or recovery certificate before boarding. In addition, EU rules on non-essential travel from third countries still apply.
A list of third countries barred from non-essential travel--as well as applicable exemptions--is available online.
The grand duchy introduced the quarantine rules over fears of the Delta variant, which originated in India and quickly spread across the globe. It is now the dominant variant in Luxembourg, too, responsible for 99.5% of new infections.
Similar rules applied to arrivals from the UK but were lifted at the end of July.
