Can a woman travel alone, if the journey is less than 24 hours and is by plane?
Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
A woman is not permitted to travel without a Mahram (unmarriageable one) for the distance of 83 k.m, whether she travels by air or any other means. Furthermore, passing through the distance fast or slow has no effect on the above ruling.
In this vein, the Prophet (Sallallahu Alaihi wa Sallam) said: "It is forbidden for a woman who believes in Allah and the Last Day to travel for a one-day and night-journey without a Mahram" . [Reported by Imams Bukhari and Muslim ]
Allah knows best.
