Act as a visionary concept artist with 10+ years of experience in sci-fi and futuristic design. Create a highly detailed, photorealistic image of a groundbreaking airport set in the year [2150]. The scene features sleek, gravity-defying floating runways illuminated by neon-blue anti-gravity emitters, with [modular passenger pods] gliding seamlessly between terminals. The foreground showcases an [AI customs checkpoint] where holographic interfaces and robotic attendants process travelers with biometric scans. In the background, towering [carbon-neutral skyscrapers] with vertical gardens frame the horizon, and solar-powered air taxis hover in formation. Use a dynamic dusk lighting scheme with vibrant purples and oranges reflecting off the glass-dome terminals, emphasizing the fusion of advanced technology and eco-conscious design. Include subtle details like travelers in smart-fabric suits and AR navigation displays to enhance the futuristic vibe.
