How we helped a TravelTech company redefine flight search through comfort and clarity
the project
FCF is a flight search engine designed to help travelers find the best tickets fast with maximum comfort and minimum hassle.
Most flight platforms overwhelm users with clutter and complexity. FCF approached Lazarev.agency to change that – creating a clean, intuitive, and emotionally effortless experience that makes finding the right flight simple and smart.
The challenge was to balance rich functionality (filters, insights, reviews) with visual clarity across devices. Through deep UX research, we identified two key traveler types: budget-focused and comfort-driven and built a design that serves both with precision, personalization, and ease.
The Project’s
Discovery Phase
Crafted a functional start page that converts
Because flight bookings often happen on the go or at the last minute, FCF’s homepage needed to feel effortless.
We stripped away all visual noise, keeping the interface minimal and distraction-free, while still leaving space for new features and dynamic content.
Unlike typical flight search engines, FCF doesn’t just compete on price. It emphasizes comfort and quality of experience. That’s why we incorporated comfort-centric UI elements such as visual comfort indicators, seat quality hints, and flexible filtering options right from the start page.
The result is the interface that feels as calm as it is capable, users instantly know where to look, what to do, and how to get there fast.
5 Travel & Event UX/UI Design Mistakes and How to Avoid Them
Built a search experience for real travelers
At the heart of FCF is its search and comparison flow. We crafted a system where users can refine their search by multiple parameters from layovers and duration to comfort level, airline reputation, and in-flight amenities.
Our team designed dynamic filters that respond in real time, ensuring every selection updates the results instantly.
The layout adapts smoothly to each traveler’s intent, showing essential data for quick decisions and offering deeper insights for those who want to explore more.
This approach reduces cognitive load and creates a fluid journey from search to selection.
Created a mobile experience that feels effortless
The majority of FCF’s traffic comes from mobile, so the mobile UX was treated not as an adaptation — but as a core product experience.
The Lazarev team developed a light-themed mobile interface featuring soft contrasts, airy spacing, and intuitive thumb zones. All core elements: search bar, filters, and results, fit neatly within a single screen, keeping users focused while maintaining access to advanced settings.
Every interaction was designed to feel instant and responsive, mirroring the speed users expect when planning trips on their phones.
