Women traveling alone

Dear scholars, As-salamu `alaykum. I am asking this question on behalf of my mother. She is in her menopausal age, around 52, and she wishes to go for Hajj. None of her mahram is going with her. She is going with her female cousin and the cousin’s son, whom mother is considering as her mahram. Is this OK? She really wants to go for Hajj. Please guide us.

As-salamu `alaykum. Is it obligatory for a husband to accompany his wife on her Hajj, or is Hajj obligatory according to each person's own responsibility? I am not only speaking about the economic factor but also the necessity of accompanying my wife.
