is it permissible for women to travel by plane without a Mahram

QUESTION:

My question is: it permissible for women to travel by plane without a Mahram? Sometimes I cannot go with my wife to her parent

ANSWER:

Due to necessities and circumstances it would be okay for her to travel without a Mahram providing the journey does not last for more than three days, if the journey takes less than a day it would be better.
Hadith:
It is not permissible for a women who believes in Allah and the last day to travel for three days or more except that she be accompanied by her Father, son, husband, brother or any Mahram. (Sahih Muslim)

And Allah Ta’aala knows best
