1) Qatar Airways has implemented a color-coding system to help passengers navigate the airport in Doha. Passengers receive color-coded boarding passes and bag tags that correspond to the terminals and activities.
2) The color-coding is applied consistently across touchpoints from check-in, on the plane, on shuttle buses, and at the terminals. Clear signage and staff help guide passengers of each color.
3) This system effectively conveys information through multiple channels without relying solely on language. It helps passengers smoothly transfer between flights in the large airport of Doha.
