Air India is reserving part of its economy section for women only, in order to combat harassment, in a first for airlines.

Only women who are flying alone will be able to reserve these seats at no additional cost starting Jan.

18.

Women booking in groups or traveling with families will not be able to purchase the seats, of which there are only six.

The airline has not said how it will enforce this policy.

An Air India official said, "We feel, as national carriers, it is our responsibility to enhance comfort level to female passengers.

" So what inspired the new measure? Some recent in-flight harassment allegations may be to blame.

In December a man allegedly groped a sleeping female passenger during a flight to Mumbai from Newark.

And, this month, an Air India flight attendant reported that she was molested by passenger on a flight to Muscat.
