I would like to travel back home – domestic flight. My trip was not for pleasure, it was only for chessed. Should I be worried about traveling during the 9 days
You can travel back home. Taking a domestic flight is permitted according to some poskim, and even according to those who discourage air travel, they agree that it is permitted to travel for a mitzva. Although you are not traveling home for a mitzva, it is included in the in the mitzva.
