It's not just flights: Saudi Arabia are basically starting a blockade. They're closing the land border with Qatar and banning shipping too. Qatar gets a lot of its food supply from SA so it's going to be in difficulty almost at once. This seems very likely to drive Qatar (further) into the arms of Iran – it's not obvious how that will help stabilise the Gulf region.
