The PIA or Pakistan International Airlines has two flights a week between Mumbai and Karachi.

PIA had cut down its flights because of poor traffic amid increasing strain between the two countries over the past year.

Days later, India targeted terror launch pads or staging areas for Pakistani terrorists in a surgical strike across the Line of Control.
