It is still largely symbolic - in last few months Lukashenka has implemented various travel restrictions with the west (both for political reasons and also to limit emigration/brain-drain as e.g. various IT companies were relocating Belarus employees to Poland/Lithuania/etc) and there was a feeling that he might have restricted flights or the ability to fly anyway - so now the same result gets achieved not by the prohibitions of the regime but can be blamed on the "evil neighbours". It's perhaps somewhat similar to sanctions against Russia which were followed by Russia-imposed sanctions on importing e.g. cheese, which has the benefit of improving trade balance (as people aren't consuming imported products) and any discontent of the people is blamed on the western sanctions; the regime wants to ban certain things but it has less impact on people's satisfaction if the ban can be blamed on everyone else.
