In a world-first move, India’s biggest budget airline IndiGo is shaking things up by offering women the choice to avoid sitting next to men on their flights. Starting this August, the airline is rolling out a new feature that lets female travelers see the gender of their potential seatmates during online check-in. This means women can now opt to sit next to other women if they prefer.

Interestingly, men won’t have the same visibility when booking their seats. IndiGo, which partners with Qantas and is popular for traveling to and within India, introduced this feature after a survey revealed that many female passengers would feel more comfortable with this option.

India isn’t new to gender-specific seating—female-only carriages on local trains have been a thing for a while now—so it’s not too surprising to see this concept take off in the skies. Women-only transportation options aren’t unique to India; several other countries have implemented similar measures to enhance safety and comfort for female travelers. In Japan, women-only train cars are a common feature on many commuter lines, particularly during rush hours, helping to reduce instances of harassment in crowded spaces. Mexico City introduced women-only buses and subway cars as part of their efforts to combat gender-based violence on public transit. Similarly, in Egypt, women can choose to ride in designated women-only carriages on the Cairo Metro. These initiatives reflect a broader global trend of addressing women’s safety concerns in public spaces by providing gender-segregated options.
