Regardless of the airline you will need proof of a negative covid test to fly into Belarus:
Passengers must have a printed medical certificate with a negative Coronavirus (COVID-19) PCR test result issued at most 72 hours before arrival. The certificate must be in Belarusian, English or in Russian.
This information was updated on October 23 and from the list of press announcement travel restrictions have been changing quite frequently. Check the info often as your travel date approaches. Also I advise you to have a printed copy of the latest rules with you. I recently traveled to Europe and found that nearly every agent had read a different version of the rules. When I insisted each time, showing them the latest information, they allowed me to go through either right away or after validating with a supervisor. Even the arrival form handed before landing on the plane was outdated and I had to explain that rules recently changed.
