Prefers KAYAK0 vs 100

“KAYAK presents a clear, customer-facing travel metasearch product with broad features (flights, hotels, cars, price alerts, trip management) and obvious use cases for consumers planning travel. The 'Bot or Not?' content is ambiguous and appears as an intrusive bot-detection/captcha flow rather than a standalone product offering—poorly communicated, limited in scope, and with noticeable UX/accessibility friction.”
