Is communication only possible through speaking or sign language? Isn't connecting with cities through exploring and savoring them a way of communication? As #IstanbulAirport, we care about them and offer services in sign language. We celebrate International Day of Sign Languages on September 23. #iGACares 💙✈️ @gokceaydoganarman 👉https://youtu.be/WVrxe7Aa__4
