This airline lets women avoid sitting next to men

The concept of checking in and choosing your seat before you board a flight is nothing new.

However, this Indian airline is taking it a step further.

IndiGo Airlines has introduced a new feature that allows women to avoid booking a seat next to men on flights.

Speaking to CNBC Travel, the airline said passengers must identify their gender when purchasing tickets. 

During the online check-in process, seats on the seat selection page will appear pink if it will be occupied by a female passenger.

The airline said male travellers will not be able to see this information.

IndiGo began rolling out the service in May on a pilot basis and it is now available on all of its flights.
