COVID-19 Fit to Fly Certificate

Most airlines now ask travellers to provide evidence of a recent negative COVID-19 test before boarding a flight. Our Fit to Fly certificate can be used as proof of a negative COVID-19 test.

Please check the requirements of your airline or destination before travelling. Rules on when you need to take your test, the type of test and certificate details can change at short notice.

ZAVA’s Fit to Fly kit uses the PCR (RT-PCR method) swab test. This is the medical gold standard and the same test used by the NHS and Public Health England. It’s also accepted by all major airlines and embassies.

Next day delivery: Get your test kit the next day if you place your order before 4pm Monday to Friday (excluding bank holidays).

Fit to Fly within 48 hours: If you test negative for COVID-19, you can download your Fit to Fly certificate within 48 hours of returning your test by post. See 'Returning your completed test' below for more information.

We recommend ordering your COVID-19 Fit to Fly test kit at least 7 working days before your flight. You will need to wait until the deadline to take your test sample. The deadline depends on your travel destination but is usually 72 hours or 96 hours ahead of your flight.

Your destination country will have specific rules on when to test before your flight. So don’t forget to check with your travel provider or airline.

You can also visit Gov.uk for more information, including regular updates.

Post your sample to a Royal Mail priority post box using the prepaid Tracked24 envelope included with your test. Your results will be ready within 48 hours if you return by post. IMPORTANT: If returning your test via post, please check the collection time for the priority post boxes near you to make sure you post before the last priority collection. Failure to do so may result in additional delays. Check priority post box times.

Please make sure you note down your tracking number before returning your sample. You will need this to track when your sample has been delivered to the laboratory. If you find that it has not been marked as ‘delivered’ within 24 hours, please contact our Customer Support Team. We do not take responsibility for any sample being lost in transit.

Where you’re travelling will affect when you need to take your test and when you’ll need your certificate, so make sure you check your destination guidelines before getting started. You can look up the requirements for the location you’re travelling to on the Foreign Travel Advice pages on Gov.uk.

If you’re unsure or worried that your flight times don’t allow for your results to be ready, you can call our Customer Support team for advice.
