Following things should be kept in mind by all the ladies who are traveling alone:

1) Trust your instincts: If you feel something is wrong scream, flee or do what ever you feel is appropriate.

2) Body language: proper body language plays a very important role

3) Try to sit or stand next to other women or family groups

4) Clothing should be both fashionable and appropriate

5) Carry enough money in your shoe or money pouch.
