It would be legal to ban people on flights with specific types of criminal records showing a possible risk for other passengers. Constitutional law would regard eliminating all Muslims from flight as discrimination due to religion. Trump would not win that court case in a higher court. It is blatantly discrimination because it is holding an entire category of people accountable for the actions of a few others in their category.
