ROUTE UPDATES: Argentina approval of scheduled international flights only every 15 days

After reductions to international flights in late January and again in late March, the  Argentine government's control of flights has evolved to the point of approving them only in 15-day blocks coinciding with the first and second half of each month, instead of one month at a time as had been the practice since December, almost reverting to the practice of approving flights on a "special" basis as it did between March and October 2020.  

The resulting uncertainty about which flights will actually operate has caused great difficulty for the airlines and passengers alike as they can only plan on a tentative basis.
