On 28 april 2017 i was traveling from mumbai chatrapati shivaji airport to calicut. My 11 year old son vomitted and i had to take him to the ladies toilet. I was washing my hands suddenly an indigo staff commanded my son to stand outside or else the crew may complain about it. But at the same time many of the crew also entered before her and had no problem with my son.
I want to ask the indigo authorities if i can use the gents toilet with my son in such a situation. I would like to tell her that the rules of a mother is beyond the rules of indigo staff. I would also like to stress that she was so impolite and arrogant on her behaviour.
