Hikitia Air – Airline Booking UI & UX Case Study

Hikitia Air is a UX case study from my UX Design Institute program. It explores how to improve the online airline booking process through user research, testing, and prototyping. The project prioritizes clarity, simplicity, and efficiency.

✈️ During my studies at The UX Design Institute, I conducted a full UX case study for a fictional airline called Hikitia Air. My goal was to improve the digital airline booking experience — streamlining it to be fast, intuitive, and genuinely helpful to users. From research to prototype, I took on every role in the UX process.


🔍 Competitive Benchmark

Before jumping into design, I studied top airline booking platforms to understand what they’re doing right (or wrong). Key questions I explored:

  • What UX patterns are working well and worth adopting?
  • What pain points keep recurring across platforms?
  • What standards should I incorporate into my own flow?

🧪 Usability Testing

I ran usability tests on real airline websites to capture user behaviors, habits, and frustrations. A few takeaways:

  • Users browse flights on mobile but prefer booking on desktop.
  • Incomplete or scattered info causes user hesitation.
  • Fare breakdowns were often unclear or misleading.

🧠 Affinity Diagram

Once research was gathered, I organized insights into themes using an affinity diagram. This helped synthesize findings and identify clear priorities for design.

  • Observations from benchmarks, surveys, and tests were written on sticky notes.
  • Grouped into thematic clusters in Miro.
  • These categories informed both the Customer Journey and User Flow.

🧭 Customer Journey Map

I created a detailed journey map to visualize the user experience from start to finish. This made it easier to spot friction points and opportunities for improvement.

🧩 User Flow

The user flow mapped out the ideal booking process and ensured every UX decision was based on real user insights.

  • Covers the high-level steps in booking a flight
  • Solves pain points identified in the journey map
  • Prepares the foundation for wireframes and prototypes

✨ High-Fidelity Prototype (Annotated)

I designed a high-fidelity prototype in Figma, integrating all research insights into one polished interface. It’s designed to be clean, efficient, and user-first.

🎯 Results

This project was a comprehensive deep dive into UX design — from raw research to an interactive, high-fidelity prototype. It taught me how to ask the right questions, design for real users, and build experiences that are both delightful and efficient.
